A CLINICO-PATIIOLOGICAL STUDY OF INJURIES OF TI1E HEAD, WITH SPECIAL REFERENCE TO LESIONS OF THE BRAIN SUBSTANCE* By CHARLES PHELPS, M. D., SURGEON TO BELLEVUE AND ST. VINCENT’S HOSPITALS. Two years ago I read before this association, in the course of a general discussion upon cerebral surgery, a very brief paper upon cerebral contusion. Since that time a very considerable number of cases of serious injuries of the head, almost all of which have involved lesion of the brain substance, have come under my observation. They pre- sent so many points of interest and importance that I have ventured to ask renewed attention to an extension of the same subject. In no department of surgery are more problems yet unsolved, and in no department are the re- sults of careful study likely to be of more absorbing interest or of greater professional value. Attention has been largely directed to cerebral localiza- tion, and to certain surgical procedures founded upon the * Read before the New York State Medical Association, November 16, 1892.

Such operations upon the brain have been conspicuously successful, and have been justly reckoned among the triumphs of modern surgery. When guided by the disclosures of physiological experi- ment and aided by the application of recognized aseptic laws, operations upon the brain have been devised and suc- cessfully executed which in the immediate past would have been not only impossible but incredible. It is equally true that these operations are still limited in number and application. The instances in which brain lesions can be ac- curately defined and located and afterward made subject of operation with reasonable prospect of success are compara- tively infrequent. The lesions which are of such nature, so well defined in outline, or so situated, in view of demon- strated localization of brain function, that their diagnosis can be made with reasonable certainty, are few enough in the first instance; those which are within reach of the surgeon’s knife are fewer still; and those in which the patient ulti- mately survives constitute but a small proportion of the originally scanty number. It is not strange, however, that operations which invade the very penetralia of the human organism should fascinate by their audacity, and that, when successful, they should dazzle the modest workers in more prosaic fields of labor. It is also possible that the ardor with which the diagnosis and relief of local lesions of the brain have been pursued, in the light of functional localization, may tend to distract attention from those general patho- logical conditions which are of so much greater frequency. The study of cerebral topography, moreover, has been so much more effectively prosecuted by the physiologist than by the pathologist, that perhaps the results of clinical and pathological work have been practically if not theoretically underrated. It is certainly proper at the present time to more generously supplement physiological experimentation INJURIES OF THE HEAD. 3 by both ante-mortem and post-mortem observations made upon the human subject. For this purpose, cerebral trau- matism, which this series of cases illustrates, affords pecul- iar advantages, since death results from the establishment of lesions in a previously healthy brain, and since it pre- sents itself with sufficient frequency for purposes of com- parison. The cases which I propose to subject to analysis are one hundred and twenty-four in number, and, with two or three exceptions, have been previously unreported. They have occurred mainly in my service in two hospitals, and in the last two years. They include all cases of injuries of the head which I have seen during the time specified, and if they are preponderatingly of one character, they are proba- bly still representative of the whole class to which they be- long. Wounds of the scalp have not been included because they are not only surgically insignificant, but have no ne- cessary relation to the deeper-seated injuries which it is proposed to consider. In a previous paper upon a subject of an entirely different character, I found it convenient to ab- stract the histories of the several cases upon which it was based. I pursue the same course in the present instance in order to afford a means of verification of such conclu- sions and generalizations as I may establish, and at the same time to make record of a large amount of material which may be of service hereafter to students of the same class of injuries. 1 shall not attempt a reading of these histories, but shall leave them to appear in the archives of the association for future consultation. They are arranged in accordance with the nature and result of the primary injury. FKACTURES AT THE BASE. Case I.—Male, aged forty-five; fell in the street; admitted to alcoholic ward; wild delirium, requiring mechanical re- 4 A CLINICO-PATHOLOGICAL STUDY OF straint; haemorrhage from left ear; wound in posterior parietal region; high temperature; coma; death in forty-eight hours. Necropsy.—Fracture at the base, with complete separation of the left temporal bone into its constituent parts—squamous, petrous, and mastoid. Slight laceration of left parietal lobe at a point corresponding to seat of external injury. At a corre- sponding point upon opposite parietal lobe there was extensive laceration 3’5 inches x 1‘5 inch in diameter. Case If.—Male, aged forty; said to have fallen from his truck; no superficial injury; delirium, which was considered alcoholic; refused treatment; delirium continued next day, and he committed suicide by drowning. Necropsy.—Fracture at base extending from left parietal eminence to foramen magnum. Superficial laceration of right temporo-sphenoidal lobe by contre-coup. These two cases have been previously reported. Case III.—Male, aged fifty; fell from steps to sidewalk; scalp wound in right posterior superior parietal region; haem- orrhage from right ear, and later from right nostril; coma; stertor ; rigidity of all the limbs; left pupil dilated. In twelve hours complete left hemiplegia supervened, and haemorrhage from right ear renewed. Stertor and rigidity disappeared, and left pupil became normal. Unconsciousness and incontinence of urine continued from time of admission till death from as- thenia at the end of six days. Necropsy. — Fracture at base, beginning at point of injury and extending through right petrous portion and middle fossa to apex of opposite petrous. Lacerations of left frontal and right temporo-sphenoidal lohes interiorly and laterally. Thick clot over left frontal and temporal lobes laterally, growing thinner as it extended toward base and vertex. Whole brain intensely hyperaemic Case IV.—Male, aged twenty-two; cause of injury un- known; compound depressed fracture external to right parietal eminence; semi-comatose, irrational, articulation indistinct; respiration continued slow and irregular for three days. The depression was found on trephination to be of the external table only. Two days after admission, complete paralysis of ex- INJURIES OF THE HEAD. 5 tensors of right hand, paresis of right arm, and right facial paralysis, involving both mouth and eyelid. All these paralyses afterward varied in degree from time to time, and the mental condition varied from rationality to noisy delirium. He was usually restless, and became unconscious for two days before death. Temperature on admission, 101°, and remained above 100° for a week. Then declined to 99°+ during another week. Two days before death it rose steadily from 103° to 109°. Died in forty-five days. Necropsy.—Fissure extending from point of depression into right middle fossa. Subacute arachnitis and excessive cerebral by persemia; surface of brain at point of fracture unchanged, but beneath it was a large cavity containing reddish semi-fluid ma- terial, and brown detritus from subcortical laceration. Case V.—Male, aged thirty-five; cause of injury unknown ; scalp wound over occipital protuberance; patient under influ- ence of drink; would not answer questions; grew stupid, and in three hours became unconscious; mechanical restraint neces- sary. Temperature soon after admission was 102°, and in ten hours became 105°, receded to 101*8°, and then rose steadily to 10f)'6°. He died twenty-nine hours after admission. Necropsy.—Haematoma covered whole calvarium. No frac- ture of vertex, but a slight fissure existed along the posterior border of the right petrous portion of temporal bone from contre- coup. Thin coagulum and fluid blood covered upper surface of both cerebra (meningeal contusion). Lacerations of under surface of left frontal (large) and temporo-sphenoidal, of inner border of right frontal, and of under surface of right temporo- sphenoidal lobes. The last was as large as a hickory nut. Case VI.—Male, aged thirty-eight; knocked down by a blow upon the head from a club; scalp wound in right parietal re- gion. He was stupid, and could not answer questions coher- ently. Left pupil slightly dilated and eyes directed slightly to the right. Next day incoherent, delirious, and had delusions and muscular tremor, pupils irregular, pulse frequent and inter- mittent. Temperature on admission 103°, five hours later 102°, rose to 106'2°. Died in twenty-four hours. Necropsy.—Linear fracture through whole length of right 6 A CLINICO-PATHOLOGICAL STUDY OF parietal, right occipital, and petrous portion of temporal bone into middle fossa. Considerable laceration of under surface of left frontal and temporo-spbenoidal lobes. Case VII.—Male, aged forty-five; fell upon the sidewalk, striking the back of the bead. Admitted after twenty-four hours. (Edema under and about an old cicatrix behind the right ear, and underneath this an extensive comminuted frac- ture. Two pieces of bone were removed and one elevated, and a large, firm epidural clot extracted as far as possible. The patient was in a condition of stupor; pupils irregularly dilated ; articulation difficult; muscles generally rigid; gait ataxic when he attempted to walk; sensibility diminished; and urine incon- tinent. His condition improved for four days after operation; temperature decreased, mental condition became clearer, and muscular rigidity lessened. There was copious serous discharge from the right ear, followed by right facial paralysis. On the fifth day temperature rose from normal, muscular rigidity again increased, and he again became stupid. The next day he be- came unconscious, and in an hour’s time he had eighteen general convulsions, and died the following morning. His temperature did not exceed 99‘8° till the fifth day. On the morning of his death it was 105°. Necropsy.—Fracture at the base. The whole central portion of the occipital, from the foramen magnum upward, and poste- rior portion of both parietal and right temporal bones, forming an irregular circle two inches and a half to three inches in diameter, were broken into large fragments, two of which had been removed during life. The mastoid and outer part of the petrous portion of the right temporal bone could be removed by the fingers with the use of very little force. This line of fracture ran through the tympanic cavity, so that, after removal of the outer fragment, the carotid canal and aqueductus Fallopii could be seen in the section filled with coagula. A large epi- dural clot was situated beneath the occipital fracture, extending half an inch beyond its margin. A large subdural clot filled the right inferior occipital fossa, extending to the foramen mag- num. The cavity of the posterior part of the great longitudinal sinus was occupied by a thrombus, and its walls were infiltrated INJURIES OF THE HEAD. 7 with blood. There was a large, partially decomposed thrombus in the torcular Herophili, extending through the right lateral into the petrosal sinus and internal jugular vein. The whole internal surface of the dura beneath the seat of the external haemorrhage was lined by a firmly coagulated clot, with an in- flammatory exudation around it. A portion of the surface of the right occipital lobe posteriorly was softened, showed minute haemorrhages, and was torn away in the removal of the dura. The meshes of the pia mater over a large part of the parietal and occipital lobes posteriorly were distended with slightly tur- bid serum. There was a small laceration on the under surface of each frontal lobe, and a larger one, three quarters of an inch in diameter, existed in the right cerebellum at a point cor- re-ponding to the site of the thickest part of the subdural haemorrhage. Case VIII.—Male, aged seventy-six ; cause of injury un- known ; admitted to alcoholic ward, and transferred to surgical service same day. Patient unconscious from the time he was found in the street. Stertor ; muscles rigid on both sides; both pupils very strongly contracted, the left one the more so. Scalp oed9matous in right parietal region. Fissure, extending from posterior and inferior part of right parietal into occipital bone, discovered by incision. There was no change in the general symptoms up to the time of death, two days and six hours after admission. The left pupil continued to be the more strongly contracted, and muscular rigidity continued to be more strongly marked on the right side. Consciousness was not regained. Temperature on admission, 100-4°; rose steadily to 103'8° ; post mortem, 102°. Necropsy.—Fracture at base extended to right jugular fora- men, and then turned backward to foramen magnum. Slight epidural and considerable subdural haemorrhage at point where fracture began. Slight serous effusion into pia. Thrombus in torcular Herophili, extending into right occipital sinus and through petrosal sinus into jugular vein. The whole inferior surface of the brain covered with blood. Superficial laceration along the anterior border of left temporo-sphenoidal lobe from median line outward. Large clot could be seen bulging out- 8 A CLIXICO-PATHOLOGICAL STUDY OF ward, behind a thin cortical layer, along the whole length of external border of left frontal lobe. Well-marked lacerations upon anterior border of both frontal lobes, and also upon their inferior surfaces along the longitudinal fissure. Optic chiasm surrounded by a clot, which extended backward as far as ante- rior border of the pons Yarolii. Upon section along external border of left frontal lobe, a clot of great size was disclosed, which occupied almost the whole substance of the left frontal and temporo-sphenoidal lobes, from the third frontal convolu- tion backward. This haemorrhage had broken through into the lateral ventricles and thence into the occipital lobes, which were also filled with great pools of fluid blood. Case IX.—Male, aged forty ; fell into the hold of a vessel; semi-conscious when found; haemorrhage from both nostrils and from right ear; regained consciousness next day ; four days later delirious and irritable; back of neck rigid; abdomen re- tracted ; death at end of five days. Cheyne-Stokes respiration supervened. Temperature for seventy-two hours, 99'2° to 99-8° ; fourth day, 103*2°; fifth day, 104‘8°. Necropsy.—Contusion over right mastoid revealed on raising the scalp. Fracture at base in three fissures; extending from this point, two (fine) across petrous portion, and a third con- necting them posteriorly across occipital bone. Deep linear laceration, extending across inferior surface of right cerebellum, near outer border. Subdural haemorrhage over whole left cere- brum, superiorly and laterally; most copious in middle lateral region. Laceration of antero-inferior border of left frontal lobe. White substance of left cerebrum much congested, and with punctate extravasations throughout its extent. Case X.—Female, aged eight; fell two stories; partially un- conscious; left hemiplegia, and haemorrhage from left nostril; depressed fracture over left frontal eminence. Patient became irritable, and the hone was elevated an hour later. Died with- in twenty-four hours. Necropsy.—Coronal suture separated on the right side. A fissure extended through right parietal eminence and another through frontal bone. Base fractured across body of sphenoid into left middle fossa. Other fissures through right middle and INJURIES OF THE HEAD. 9 anterior fossae, external to orbital plate. Epidural haemorrhage on left side anteriorly and in temporal region. Lacerations in right frontal lobe and in right fissure of Rolando and in left temporo sphenoidal lobe. Case XI.—Male, aged twenty nine; fell fifteen feet into the hold of a vessel and struck on his head. Coma, stertor; left pupil markedly dilated and right pupil contracted; para- plegia, haemorrhage from left ear and nose and under left con- junctiva, and contusion over left eye. Died in five minutes after admission. Necropsy.—Epidural haemorrhage, blood still fluid. Frac- ture extending downward and forward from behind left parietal eminence, across petrous portion, through middle fossa, trans- versely across anterior fossa, and terminating at inner extrem- ity of lesser wing of right sphenoid. Slight cortical haemorrhage on left side, and slight lacerations of under surface of left frontal and temporo-sphenoidal lobes. Case XU.—Female, aged twenty-three; jumped from fifth- story window. Contusions of left hip and shoulder and over right parietal eminence; slight haemorrhage from nose and left ear; temperature, 99-4°; incontinence of urine and faeces; right hemiplegia. Death in two days. Necropsy.—Fracture extending from right parietal eminence to foramen magnum, of right petrous portion entire length, and of left petrous for two inches; laceration of left parietal lobe beneath parietal eminence. Case XIII.—Male, aged forty-six; fell five stories. Coma, stertor, pupils normal; pulse and respiration normal. Death in five days. Necropsy.—Contusion over right parietal eminence; frac- ture extending from this point downward and forward, anterior to petrous portion, and through sella turcica; subarachnoid haemorrhage over both hemispheres; laceration of under sur- face of left temporo-sphenoidal lobe. Case XIV.—Male, aged fifty; knocked down by a blow in the face and fell upon the back of his head. Patient became unconscious, but shortly afterward walked to the hospital ; contusion over right parietal eminence; dazed; no other symp- 10 A CLINICO-PATHOLOGICAL STUDY OF toms; walked home; had severe pain in the head for three hours after the injury, then became gradually unconscious till four hours later, when coma was complete and death occurred at the end of another hour. Necropsy.—Wound of lip and contusion of forehead; fissure of external table, very fine, beginning in right inferior occipital fossa and running across right petrous portion ; slight epidural haemorrhage about the middle of the fracture; upon left side, large subdural extravasation upon lateral border of parietal and frontal lobes, extending upward and also downward into middle fossa; also some extravasation into pia and several slight contusions of brain substance; skull thin, and angles and processes upon its inner surface unusually sharp and prominent. Case XV.—Male, aged forty; cause of injury unknown. Coma; respiration slow and full; right pupil dilated, left con- tracted ; reflexes lost; had been seen to move the left side; pulse became slower and breathing more labored. Died in nine hours and a half. Necropsy.—Contusion in left parietal region; fracture from this point extending by two fissures into anterior and middle fossae; large epidural haemorrhage from rupture of left middle meningeal artery ; slight laceration of left parietal lobe at point where fracture began, and another upon lateral border of right temporo-sphenoidal lobe. Case XVL—Male, aged fifty-five; fell upon the street. Unconscious; respiration labored; left pupil slightly dilated; slight haemorrhage from left ear; slight rigidity of left side. He was still stupid upon admission, but could give his name. Temperature, 99°. Dilatation of left pupil and rigidity of left side increased, and afterward there was complete paralysis of left lower extremity, while left arm remained slightly rigid; left hemiplegia was finally complete. He died in twenty-one hours. Temperature, 101-2°. Necropsy.—Contusion of scalp over left occipito-parietal suture; skull thin; stellate fracture, originating about the cen- ter of left parietal bone; fissures extending upward, across base of occipital and along the upper border of petrous portion of temporal bone into the middle fossa; subdural haemorrhage INJURIES OF THE HEAD. 11 covered right hemisphere; under and lateral surfaces of right temporo sphenoidal lobe extensively lacerated; under surface of both frontal lobes lacerated along the median fissure ; these lacerations were recent; upon the under surface of the left tem- poro-sphenoidal lobe there was a deep laceration, irregular in outline, but about an inch in its several diameters; there were also small and deep lacerations upon its anterior border and upon the under surface of the left frontal lobe. All these lacera- tions upon the left side extended through the cortex, contained no recent clot, but were covered with a grayish-yellow viscid substance, and were bounded by a considerable area of yellow softening. They evidently antedated the final and fatal injury. Section of the brain disclosed marked hyperaemia. Case XVII.—Male, aged fifty; cause of injury unknown. Unconscious; pulse, 60; respiration full and slow; right pupil dilated, the left contracted, neither one responding to light; lie had been seen to move the left side of the body; stertor supervened and death occurred in eleven hours. Necropsy.—Contusion of left parietal region disclosed by in- cision; two fissures originated from this point, one extending into the anterior and the other into the posterior fossa; large epidural clot from rupture of left middle meningeal artery ; gen- eral contusion; hyperaemia. Case XVIII.—Male, aged thirteen; fell two stories. Haemor- rhage from right ear; unconscious; irritable when disturbed; consciousness regained in thirty minutes; pulse 78, intermit- tent; temperature, 98°; depressed fractures below right tem- poral ridge; elevated next day; three fissures, one backward, one forward, and one downward; dura incised; only subarach- noid haemorrhage; temperature, 101 *8°. Next day patient irri- table and somnolent; urine incontinent; temperature slightly increased (102°). On second day after operation he was de- lirious, and temperature rose steadily till evening, when it was 105-4°. On the third day the skin was hot and he was very restless and sensitive to external impressions; his pupils were moderately dilated and reacted slowly. From this time he was in deep coma; temperature varied from 104°+ in the morning 12 A CLINICO-PATHOLOGICAL STUDY OK to 105°+ in the evening till death on the evening of the seventh day, when it was lOli'S0. Necropsy.-— Skull thin. No pus in the wound or in the small brain cavity which had been disclosed by the ante-mor- tem operation when the depressed bone was elevated. Sub- dural haemorrhage in the opposite (left) occipito-parietal region. An effusion of thick green pus beneath the arachnoid covered the lateral and superior surfaces of the right occipital and parietal lobes, but did not extend forward to within an inch of the cranial opening left by the ante-mortem operation. A sub- dural effusion of similar thick green pus was coextensive with the whole right inferior occipital fossa. There was a deep laceration, an inch in diameter, upon the lateral border of the left temporo-sphenoidal lobe, which involved the subcortical tissue. At’a point directly beneath the opening left by the re- moval of the depressed bone there was a cavity in the brain substance as large as a hickory nut which opened by its whole extent upon the cerebral surface. (As this surface was intact at time of operation, the cavity must be ascribed to a direct contusion, subcortical, not involving superficial laceration, and to a subsequent giving way of the cerebral cortex under the influence of arterial pulsation, and in the absence of normal re- pressive force exerted by the skull and dura.) The whole brain substance and meningeal vessels were intensely hyper- amric, and there were numerous minute extravasations from general contusion. There was no meningeal or ventricular serous effusion. A fissure extended from the central point of fracture through the petrous portion of the temporal and infe- rior occipital fossa to the foramen magnum. Ca.se XIX.—Male, aged nineteen; fell three stories through a hatchway ; unconscious; irritable when disturbed; pulse, 80; temperature, 100°; profuse haemorrhage from left ear, which continued twenty-four hours, and was then followed by serous discharge. At the end of twenty-four hours patient was still unconscious, pupils were largely dilated and movable, and he had general convulsive movements, most marked in the right leg. During the second day coma was more profound and general convulsive movements ceased, but he had one prolonged INJURIES OF THE HEAD. 13 general convulsion, which was repeated on the third day, the movements being most violent on the left side. The left pupi. continued from the first day to be more contracted than the right. Died in three days and six hours. Temperature con- tinued to rise from time of admission, and reached 107'2°. Necropsy.—Large hasmatoma in substance of left temporal muscle. Fracture extended from left squamous portion of tem- poral bone into middle fossa, and by a wide fissure along the anterior border of the petrous portion to the sella turcica. Large epidural and subdural clots in left middle fossa. Right cerebrum covered by a thin subdural coagulum. In the left middle fossa diffluent brain substance clung to the dura as it was removed. Large and deep laceration of the lateral border of the left temporo-sphenoidal lobe and of the lateral border and contiguous inferior surface of the right temporo-sphenoidal lobe. Small and deep laceration at junction of right parietal and occipital lobes. All these lacerations extended into the subcortical tissue. Case XX.—Male, aged sixty-two; cause of injury unknown ; found unconscious in an ice wagon with his head lying on a cake of ice. Contusion of left parietal region, and both eyes much ecchymosed. Subconjunctival haemorrhage at outer part of left eye. Muttered incoherently when disturbed. Slight temporary rigidity of right arm. Restless and irritable all day, and roused sufficiently in the evening to give a name and ad- dress, both of which proved to be incorrect, Condition under- went little change till death—at the end of seven days and seven hours. Temperature high on admission—101°; in forty-eight hours, 104-6° to KM'S0; seventy-eight hours later it receded to 101-2°; in forty eight hours more it varied from 101° to 102° + , and then rose steadily to 107°+ at the time of death. Necropsy.—Skull thin; fracture of left anterior and middle fossae, apparently beginning with a comminution of orbital plate of left frontal bone about its center. At this point two or three small fragments were displaced upward with fine fissures run- ning off in different directions. One fissure ran outward and upward into left squamous portion of temporal bone; another ran backward from the crista galli through the bodies of the 14 A CLINICO-PATHOLOGICAL STUDY OF ethmoid and sphenoid, through the optic foramen and along the anterior border of the petrous portion ; and the third ran through the right optic foramen into the squamous portion of the right temporal. The optic nerves were uninjured. There was a little blood extravasated over right occipital and lower part of right parietal lobes. The left frontal lobe was completely excavated by a laceration, which was bounded everywhere by a thin layer of unaltered cortex, except interiorly, near the anterior border, where it wras covered in only by the meninges. It was separated from the ventricle by a thin saeptum of brain sub- stance. This cavity contained commingled blood, clot, and brain detritus. There was also a laceration of the anterior two thirds of the external lateral border of the right cerebellum, and an extravasation the size of a robin-shot existed in the center of the right corpus striatum. There was no clot anywhere at the base of the brain and no further lesions. Case XXL—Male, aged twenty-seven; fell seventeen feet into the hold of a vessel, striking his face and stomach. Thirty minutes later an officer found him lying upon the dock uncon- scious and bleeding from the mouth and nose. In the interval which had elapsed he was said to have been excited and abu- sive. He was seen upon the dock and twice afterward during the night at the station-house by ambulance surgeons, who re- fused to take him to a hospital, because, in their opinion, he was simply drunk and in no want of surgical treatment. The next morning he was taken to court by two policemen. He was then conscious, and, in their inexpert opinion, rational. He was unable to stand or walk, and was carried between them on their arms into a street-car and into court. He was duly sen- tenced for intoxication, but by an inspiration of somebody he was halted on his way to the Island and placed in the alcoholic ward at Bellevue. A little later he was transferred to a surgi- cal ward. At that time he was weak, his pulse slow, and res- piration labored. There was much ecchymosis of the eyes, and the lids could be separated only with great difficulty. There was subconjunctival haemorrhage of both eyes, and the arms were rigid, more especially the right. Pupils normal. The patient soon grew restless, and had muttering delirium, inconti- INJURIES OF THE HEAD. 15 nence of urine, and Cheyne-Stokes respiration. Temperature, 104-8°. Depressed fracture easily felt in right frontal bone. The same afternoon he was trephined, and the fracture found to be stellate, with a depression an inch by half an inch in diameter. The inner table was driven through the dura. Pulse and respi- ration temporarily improved, but he grew weaker, and died eight hours after admission to the ward. Temperature, 106°. Necropsy.—I am indebted to the report of Dr. W. S. Jen- kins, late of the coroner’s office. There was a linear fracture in the temporal bone three inches long, extending upward and backward from the anterior margin. There was a stellate fracture in the frontal bone to the right of the median line and an inch above the superciliary ridge. On the inner surface of the skull the fracture extended across both orbital plates, through the ethmoid and body of the sphenoid bone, and on both sides through the anterior fossa and through the left middle fossa nearly to the petrous portion of the temporal bone. The nasal bones were also fractured. These fractures were nearly all comminuted. There was no considerable haemorrhage in the cranial cavity. The upper surfaces of both hemispheres were lacerated, especially at seat of fracture. Case XXII.—Male, aged thirty-nine; fell from mizzen-top to deck, and struck upon right temporal region; admitted half an hour later; unconscious, and bleeding from right ear; ster- torous breathing; pulse full and bounding; lacerated wound in right parietal region. He had pulmonary oedema, for which he had already been bled from the arm by the ship’s surgeon. Died in two hours. Necropsy.—Haematoma over Avhole right side of the head. Multiple fissures of the base (six in number), involving both sides and all the fossae. The primary fissure, of five which were connected, began as a wide fissure behind and a little to the left of the foramen magnum, and narrowed to a hair’s breadth as it ran forward to the right superciliary ridge. A sixth and entirely independent fissure ran backward from the crista galli on the left side through the optic foramen to the sella turcica. There were slight lacerations of under surface of both frontal and right temporo-sphenoidal lobes, which occa- 16 A CLTNIOO-PATHOLOGICAL SIUDY OF sioned slight subdural haemorrhage. Upon the upper and lat- eral surfaces of the hemispheres, especially the left, and at the base, an epidural haemorrhage of larger size existed in the infe- rior occipital fossae, and pressed upon the pons and medulla. Case XXIII.—Male, aged forty; found at foot of cellar stairs, unconscious and restless, with a large lacerated scalp wound, which had bled freely, and several wounds of the face. Admitted to the alcoholic ward on the diagnosis of ambulance surgeon of another hospital, still unconscious. The scalp wound was in the parieto-occipital region, to right of median line, and the most extensive face wound was over the right malar bone. As he did not “ clear up,” he was transferred to a surgical ward four days afterward. He was then nearly comatose, quiet un- less disturbed, his pupils normal, and respiration slow and regu- lar. Temperature, 102'2°; pulse, 96. Temperature next day was 104'6°, 103‘6°, and 106°; and on the morning after it was 105° and 107°, when he died without further symptoms five days and a half after reception of injury. Necropsy.—Fracture at base, through petrous portion of left temporal bone, extending to foramen magnum. Laceration of left temporal and frontal lobes, with cortical luemorrhage. Case XXIV.—Female, aged thirty-eight; habitual criminal; jumped from the third tier of the Tombs Prison to the flagging below, thirty feet or more; punctured wound in left occipito- parietal region ; unconscious; haemorrhage from left ear; pupils moderately dilated, more especially the left; and vomiting per- sistent. Temperature, OB^0. The next morning the patient was conscious, rational, and the haemorrhage had nearly ceased. In the evening she was slightly delirious, and the following day required mechanical restraint till quieted by sedatives. Both pupils became widely dilated, the left still continuing more di- lated than the right, and they were only slightly responsive to strong artificial light. This ocular condition continued till her death. The abdomen was painful and swollen. Her mind re- mained clear, but apathetic, till the sixth day, when she fell into a stupor. On the same day all the extremities became paretic and partially anaesthetic. Up to this time the muscular power had been normal. The paresis and anaesthesia were most marked INJURIES OF THE HEAD. 17 on the right side. The pulse was rapid, quick, and feeble. A day later the left foot and right hand were less paretic, and her mind was clear, but the senses blunted. She answered ques- tions slowly and after an interval, and complained of pain in the head. On the eighth day she was restle:-s and irritable, and had some right facial paralysis, while power in the left foot and right hand was still further improved. The ninth day she was delirious and unconscious. On the eleventh day she no longer moved or spoke, and paid no attention to an explorative incision. On the fifteenth day she died from asthenia. The temperature remained below 100° till the close of the fourth day, when it rose to 103°. After that it varied from 100° to 102°+ ; usually was 101°+ till the twelfth day, when it rose to 104°, and was from 103° to 104*5° till she died. Necropsy.—Head large and unsymmetrical, and skull thick. No lesion of the scalp or of the bone before removing the cal- varium. The occiput was disproportionately large, and the right occipital fossae were much larger than the left. The left middle and anterior lossae were rather larger than the right. A fissure began at a point in the squamous portion of the left temporal bone, beneath the external wound, and, passing through the anterior surface of the petrous portion, terminated in the optic foramen. This fissure was not open, but the fragments were quite movable. There was no epidural haemorrhage, but pressure was made upon the facial nerve by interosseous haem- orrhage as a result of the fracture. There was no meningitis, and scarcely the usual amount of serum in the meshes of the pia. There were slight lacerations upon the under surface of the right temporo-sphenoidal lobe, and one larger upon its external border, from which a moderate amount of blood had spread upward over the occipital lobe, barely reach- ing the parietal. Upon section, the cerebral vessels were found to be distended with blood, which flowed from the puncta vasculosa. The veins could be seen in congeries and filled with coagula. The brain substance was softened and oedematous, so that the serum followed the knife. The ventricles were dis- tended with serum. Subsequent microscopic examination of the bruin tissue in the recent state disclosed no inflammatory 18 A CLIXICO-PATIIOLOGICAL STUDY OF changes. There was a considerable extravasation of blood be- hind the peritonaeum on the right side, but no injury of the viscera. There were no serous effusions in the cavities of the body, and no chronic visceral lesions. Case XXV.—Male, aged thirty-seven. Cause of injury un- known; scalp wound in right posterior temporal region ; haem- orrhage from right ear; mental condition stupid, but conscious- ness retained; incontinence of urine and faeces. The patient had been drinking to excess. On the next day he had active delirium, with tremulous muscles and delusions and intervals of semi-unconsciousness. On the sixth day there was general mus- cular rigidity, stertor, and muttering delirium. The right pupil was slightly contracted, with slight serous discharge from right ear and slight right facial paralysis. Unconsciousness followed. On the eighth day there were two slight convulsions involving both arms, the face, and eyes. The face was drawn to the right and the eyes turned upward. Paralysis of right arm and face succeeded, and a little later the surface temperature of the left side was found to be 102°, while that of the right side was normal. Rectal temperature, lOS^0, which soon declined to 104’8°. Death two hours later. Post-mortem temperature, 106°. The temperature varied from 100° to 102° till fourth day, then from 103° to 104° to last day, when it was as noted above. Necropsy.—Fissure across petrous portion of right temporal bone. Large subarachnoid serous effusion. Thin cortical layer of blood covering whole of parietal and occipital lobes on both sides of the brain. Meningeal vessels congested. Brain struc- ture everywhere oedematous. Minute vessels filled with coagula. Fluid blood in anterior cornu of left lateral ventricle. Lacera- tion of upper and outer surface of right frontal lobe, and upon upper and outer surface and posterior border of left occipital lobe. A third laceration existed at the base of the brain upon either side of the median fissure of the cerebellum. Neither of these lacerations was larger than a walnut, and neither involved a rupture of the meninges, though they all reached the surface of the brain. Case XXVI.—Male, aged twenty-three, thrown from a INJURIES OF TIIE HEAD. 19 wagon. The ambulance surgeon found him dizzy and feeling ill. He had no other symptoms except a scalp wound in right temporal region. After admission to hospital he was entirely conscious and dictated a letter. There was haemorrhage from right ear and nostril. Temperature, 100°. No other symptom*. Soon afterward he vomited blood copiously and became un- conscious with stertor, and died in four hours from time of admission. Necropsy.—Depressed fracture of right frontal bone an inch from median line and just anterior to coronal suture, tri- angular in form with apex extending to superciliary ridge. One fissure, originating in this depression, ran through right orbital plate, and greater and lesser wings of sphenoid, into middle fossa •, another one ran through squamous into petrous portion of temporal bone, terminating upon its anterior surface. There was an epidural clot extending over lateral aspect of right frontal lobe into the middle fossa. This portion of the frontal lobe was much flattened and compressed. There was no sub- dural haemorrhage and no superficial laceration of the brain. There was a small effusion of blood in the meshes of the pia on either side of the medulla, behind the pons, parallel to the an- terior columns. The whole brain was hypertemic with a multi- tude of punctate extravasations, and the minute vessels were filled with c tagula. Upon section, a number of extravasations were found in the substance of the pons, mainly in the trans- verse fibers, but some in the longitudinal fibers of the crura. The smaller ones were of the size of a robin-shot. The largest one was half an inch long by a quarter of an inch wide, and was just below the surface on the right external border of its in- ferior surface. Case XXVI1.—Male, aged thirty; cause of injury unknown ; unconscious; coma continued till death; hasmatoma of scalp at vertex; at base, right side; slight haemorrhage from right nostril; stertor; pulse, 130, irregular and weak; temperature, 94°; rose to 102° some hours later; both eyes protruded and both pupils were dilated, left pupil most mark- edly so; some rigidity of right side; died same day in eight to ten hours after admission into the hospital. 20 A CLINICO-PATHOLOGICAL STUDY OF Necropsy.—Fracture through petrous portion of right tem- poral into the occipital bone and into middle fossa. No frac- ture of vertex. Epidural clot in right inferior occipital fossa. Thin subdural clot over both frontal lobes, especially over left, extending nearly to fissure of Rolando. Small laceration of left frontal lobe on its under surface near anterior border. Case XXVIII.—Female, aged forty-five, fell ten feet upon her head; scalp wound in right parietal region; temperature, 98-8°. Twenty minutes after admission left lower extremity became paretic, patellar reflexes lost. Three days later tem- perature suddenly rose from 99°+ to 102°. Next day patient became delirious. Evening temperature, 105-2°; following morning, 106°. Death five days after reception of the injury. Necropsy.—Fracture beginning in squamous portion of right temporal bone, extended through both anterior fossae, involving greater wing of right sphenoid and both orbital plates. Sub- dural clot, the size of a pigeon's egg, occupied the left middle fossa. Laceration of inferior surface of left temporo-sphenoidal lobe. Case XXIX.—Female, aged sixty-six; found unconscious at foot of cellar stairs; supposed to have been thrown down. Scalp wound in left inferior temporal region; left malar hone fractured and left side of face much contused; coma, stertor, and frothing at the mouth; moist bronchial rales; right pupil dilated, left pupil invisible from ecchymosis; right upper ex- tremity anaesthetic and soon became paralyzed; temperature, 101-6°. Three hours later the patient was apparently moribund. On the following day she was conscious and rational and the paralysis and anaesthesia had disappeared ; the pupils were nor- mal; urine incontinent; temperature, 99°-f. For a week’s time her condition remained practically unchanged, except that her temperature gradually rose to 108° and in the last three days gradually fell to 100°, and that the subconjunctival haemorrhage increased. Her mental condition was apathetic, and she could be rarely induced to make a monosyllabic answer to a question asked. On the eighth day she suddenly became unconscious. Her temperature rose to 104-8° and within two hours fell to 102-8°. She became weaker and died during the ninth day, her tern- INJURIES OF THE HEAD. 21 perature having again risen to 106°. Ten minutes post mortem it was lOb^0. Necropsy.—An open fissure extended through both tables of the bone from a little above and to the left of the external oc- cipital tubercle to the left foramen lacerum posterius. There was moderate subarachnoid serous effusion. There was an ap- parent laceration on the median aspect of the left frontal lobe, the real character of which only became obvious upon further examination. The interior of both frontal lobes was disorgan- ized and destroyed, having been broken down by subcortical laceration. On the left side the clot was very solid, and the external layers of fibrin on its inferior aspect were partially decolorized. It had broken through into the anterior part of the lateral ventricle and also through the cortex on the median surface, involving for a space of half an inch the motor arm area and the sensorial center below it in the gyrus fornicatus. It was this which at first sight seemed to be an independent lesion. The clot in the right frontal lobe, which was of equal size, had nowhere broken through the cortex or into the lateral ventricle. There was no cortical haemorrhage, although there was a deep laceration on the posterior border of the left cere- bellum. The interior of the brain generally was softened and reddened in patches. Case XXX.—Female, aged fifty; no history; admitted as case of apoplexy. Small lacerated scalp wound in left posterior parietal region; slight haemorrhage from both nostrils; patient unconscious; movements sluggish; left pupil dilated, right con- tracted; incontinence of urine and faeces; face flushed; visible pulsations of carotids ; fine linear fracture running toward tbe base discovered by incision ; temperature, 101°; at night, 101 *8° ; next day, 101 ’2° to 101°; then rose steadily to lC^’S0 on the next day, when death ensued, three days and a half after ad- mission, without consciousness having at any time been regained. Post-mortem temperature, 109°. On the last day of life sensi- tiveness of the corneas was markedly diminished and sensation was evidently blunted all over the body. Necropsy.—A fissure extended from left of occipital protuber- ance through posterior fossa and petrous bone to foramep ovale, 22 A CLINIC0-PATI10L0GICAL STUDY OF There was a large, firm subdural clot, three fluidounces by measurement, in the anterior fossae, and a slight subdural haemorrhage into right posterior fossa around the foramen magnum. A deep laceration extending below the cortex, on the under surface of the left cerebellum, made an excavation three quarters of an inch broad from the posterior nearly to the anterior border. Another extensive laceration deeply excavated the inferior portion of the right frontal and extended into the external border of the right temporo-sphenoidal lobe. Haemor- rhage from the latter laceration reached the vertex anteriorly and filled the fissure of Sylvius. Another laceration existed in the middle portion of the gyrus fornicatus, filled with brain detritus and coagulum, and extended through the cortex. This was oval in form and half an inch in diameter. There was some general contusion of both hemispheres, most marked in posterior portions. Case XXXI.—Male, aged forty-five; thrown from a horse and struck upon his head. He was temporarily unconscious, but on the arrival of the ambulance was able to stand, and said he felt very well. He again became unconscious on his way to the hospital. His pupils were contracted and his pulse barely perceptible. He suddenly became cyanotic and died twenty- five minutes later. Necropsy.—Haematoma of scalp in left occipital region; blood fluid; stellate fracture of calvarium with center in left upper occipital region, and with fissures extending downward into foramen magnum, forward into middle fossa, and upward and laterally; epidural clot in occipital region; subdural haemor- rhage in inferior occipital fossa compressing the medulla; ex- tensive subarachnoid haemorrhage over temporo-sphenoidal and frontal lobes on both sides, with laceration of inferior surface of right frontal and temporo-sphenoidal lobes, and in slighter de- gree of same region on the left side. Case XXXII.—Male, aged thirty-four; struck by a brick falling from the fourth story. Compound, comminuted, de- pressed fracture of the right parietal bone extending into the base; haemorrhage from right ear; patient conscious and with- out general symptoms; temperature, 100‘4°, and became normal; INJURIES OF THE HEAD. 23 depressed bone elevated; no injury of dura. After twenty- three days subcortical abscess of brain developed, with left hemiplegia and anaesthesia. Dura incised and abscess evacuated. Died sixteen hours later. Temperature, 108°. Necropsy.—Fissure through whole length of anterior surface of right petrous portion of temporal bone; no superficial cere- bral laceration; subcortical abscess cavity of small size, which had been evacuated ante mortem through the angular gyrus. This case is fully reported in the New York Medical Journal, March 29,1890. Case XXXII1.—Male, aged thirty-three; cause of injury un- known. Consciousness lost and never regained; scalp wound in left posterior parietal region; haemorrhage from left ear; both pupils dilated, but the right contracted later; pulse, 60; mus- cles relaxed and later became rigid. Death in twelve hours. Temperature on admission, 99-6° ; later, 98-6° to 100-4°; one hour post mortem, 101'2°. Necropsy.—Semicircular fracture of squamous portion of left temporal bone, with fissure extending into anterior surface of petrous portion; deep, well-defined laceration, laterally and posteriorly, of left temporo-sphenoidal lobe, from which a thick clot extended over the occipital region; brain in all its parts excessively hypersemic; on section, the surface was repeatedly bathed in blood as it was each time wiped away; no punctate extravasation or coagula in minute vessels. Case XXXLV.—Male, aged forty; said to have fallen down one flight of stairs. Scalp wound in right occipito-parietal re- gion ; haemorrhage from the nose and later occurrence of haema- temesis; unconsciousness; stertor; pulse, 96 and full; respira- tion, 18; temperature, 100°; pupils normal till just before death, when they dilated ; restlessness; incontinence of urine; temperature rose gradually to 102-6° one hour ante mortem. Died in fourteen hours. Necropsy.—Linear fracture in right parietal bone and ex- tending through middle fossa and greater wing of sphenoid; small epidural clot and larger subdural clot beneath the site of fracture ; dura ruptured ; cortical laceration an inch and a quar- ter by three quarters of an inch in anterior and inferior part of 24 A CLINICO-PATHOLOGICAL STUDY OF right parietal lobe; another laceration involved anterior half of middle temporal convolution on the same side. The whole brain very hyperaemic, most markedly so on left side posteriorly. In almost the exact center of the left cerebellum there was a laceration about the size of a pea filled with fluid blood. Case XXXV.—Male, aged forty ; fell six stories. Abrasion about left eye; unconscious; pulse and respiration too rapid to be counted; temperature, 101°; both pupils strongly con- tracted ; rigidity of both lower and the right upper extremities; temperature in articulo mortis, lOCK0; two hours post mortem, 99°+ and pupils dilated. Necropsy.—No superficial injury upon any part of the body except the abrasion noted. An extravasation of blood existed below the scalp, covering the whole left parietal region. Sepa- ration of coronal suture, left side, from about its middle point, extending outward and terminating in a fissure which, in the middle fossa, divided into two lines, one lost in the greater wing of the sphenoid, the other at the petro-mastoid junction. No epidural or subdural hemorrhages. Cortical haemorrhages from meningeal contusion—one covering left frontal and parie- tal lobes superiorly and laterally, another covering right parietal and occipital lobes on either side of their junction. No lacera- tion on the surface of the brain, or in any part, except one three eighths by one fourth of an inch in the left corpus striatum, subcortical, and at junction of middle and posterior thirds. Ex- cessive general hyperemia. Case XXXVI.—Male, aged sixty-five; fell into the hold of a vessel; haemorrhage from the ears and into subconjunctival tis- sue; conscious for twenty-four hours; both pupils dilated; temperature high; died in forty eight hours. Case XXXVII—Male, aged sixty; knocked down by a truck; scalp wound in right posterior occipital region. A linear fracture running backward and downward was discov- ered by incision. Patient unconscious and restless. Pupils con- tracted ; pulse, 66; very slight movements of right side of body; no facial paralysis; spoke only in monosyllables. In a short time right hemiplegia became complete, pulse weaker, temperature lower, and there was a slight general convulsion INJURIES OF THE HEAD. 25 lasting about ten seconds. Four hours later, coma was pro- found, pupils small and irresponsive, pulse and respiration very irregular, and restlessness ceased. The patient was trephined over left motor area. The fissure was found to extend down- ward behind the mastoid. Epidural haemorrhage disclosed, and, after incision of dura, subdural haemorrhage. He died three hours later, and eleven hours after reception of injury. Case XXXVIII.—Male, aged forty; cause of injury un- known; contusions behind both ears; free haemorrhage from right ear, and during the night from both ears and mouth; pupils contracted; pulse full and slow; breathing labored; tem- perature, 99‘2°; became 105°. He did not regain conscious- ness, and died six hours after admission. Case XXXIX.—Male, aged twenty; fell thirteen feet; large haematoma in left posterior parietal region; unconscious; ooz- ing from left ear and nose; pupils contracted, and eyes turned persistently to the right; mouth drawn slightly to the right; breathing irregular; vomiting free; extremities cold and muscles relaxed; urine incontinent; temperature, 99-5°. Soon after ad- mission haemorrhage from nose ceased, but continued from the ear. Patient could be roused partially but with difficulty, became restless, and moved his right side rather less freely than the left. Temperature, 101°. Two hours after admission breathing be- came stertorous, and tonic spasms, beginning in the right arm, became general. Two attacks of opisthotonos followed, and ceased after thirty minutes. Left pupil became the larger, while the right eye still turned to the right on exposure. Tempera- ture, 105°; pulse, 96; respiration, 32, and of the Cheyne- Stokes variety. An hour later, coma was profound, with slow and stertorous respiration. Temperature, 106‘6°. Respiration became insufficient, four to the minute, and face cyanotic. Death occurred in four hours. Pupils post mortem were wide- ly dilated. Case XL.—Male, aged thirty; fell three stories to the pave- ment; four ribs fractured on the right side; contusion over right eye, and slight right subconjunctival haemorrhage; un- conscious; skin cold and moist; pulse, 120; temperature, 100°. Pulse became weaker and respiration more labored, and death 26 A CLIXICO-PATHOLOG1CAL STUDY OF ensued in five hours and a half after reception of injury. No pulmonary symptoms. Case XLI.—Male, aged forty; cause of injury unknown; extensive contusion over right parietal region; haemorrhage from right ear and nose; unconscious; stertor; died in four hours and a half. Case XLII. —Female, aged forty-seven; fell on the street in a convulsion during a debauch ; had other convulsions before admission; left side of head and eyelid much contused ; mental condition stupid; pupils normal; breathing stertorous; pulse, 108; convulsions continued during the day and night; no in- terval of consciousness. During the morning a severe haemor- rhage occurred from the mouth without previous warning. In the afternoon pulse and respiration became frequent. The blood which came from the mouth was bright in color, non- aerated, and said to be more than eight ounces in amount. The next day the convulsions were diminished in frequency and were general, but more severe in the right arm. No initial symptom noted. Both arms were rigid and head constantly turned to the right. There were in all twenty-three convul- sions. Death occurred in thirty-eight hours. Temperature, one hour after admission, 102'4° ; morning of next day, 105'6°; later, 10T40, lOfi^0, 107'8°—the last, one hour before death. Case XLIII.—Male, aged seventeen; fell one story; large haematoma on left frontal region ; unconscious till death; haem- orrhage from nose, mouth, and left ear, and under conjunctiva of both eyes; pupils equally dilated; slight convulsive move- ments of right side soon terminating in right hemiplegia, with rigidity of left side; death from pulmonary oedema occurred in five hours; temperature, one hour before death, was 105-4°. Case XLIY.—Male, aged thirty-seven; jumped from a fourth- story window to the street while drunk; lacerated scalp wound in left posterior parietal region, and fissure running from it into posterior fossa; both pupils widely dilated; patient loud and abusive in language; slight left facial paralysis; incontinence of urine; pulse, 118, soon becoming irregular and almost im- perceptible. The patient became quiet, and a little later coma- tose. Temperature, 97 6° by rectum. Three hours after ad- INJURIES OF THE HEAD. 27 mission he had three clonic spasms of right arm at varying points. Died in six hours after admission while under ether, given for reduction of a dislocated hip. Case XLV.—Male, aged thirty; struck by a falling ladder; haemorrhage from mouth and nose, and blood and brain matter exuded from the right ear; both eyes protruded, the right eye the more so; both pupils contracted and irresponsive to light; right facial paralysis; respiration stridulous. Right pupil soon began to dilate slowly. Temperature, 100°; pulse, 93. Patient remained unconscious till death, two hours after injury. Case XLYI.—Female, aged thirty-five ; fell down stairs; admitted next day, still unconscious; ecchymosis in left poste- rior parietal region ; haemorrhage from left ear; left eye pro- truded; left pupil dilated. Temperature, 101°; pulse slow. Vomiting profuse. Next day paresis of whole right side; urine incontinent; some pulmonary oedema. On the third day rigidi- ty ot the muscles of the back of the neck. Haemorrhage from the ear continued a week, lessening in amount and becoming serous in character. Patient continued unconscious till death, at the end of ten days, from asthenia. Temperature ranged from 100° to 102° till the morning of the eighth day, when it suddenly rose from 101° to 103°. From this time it rose, with morning depressions, steadily to 107‘4° on the day of her death. Case XLVII.—Male, aged thirty-five; cause of injury un- known; found unconscious; small h asm atom a on left temple ; hfemorrhage profuse from both ears; evidence of previous haemorrhage from both nostrils; pulse scarcely perceptible; stertor; pupils both equally dilated ; complete relaxation of limbs, and no response to peripheral irritation. Left facial pa- ralysis was developed two hours before death, which occurred in six hours without restoration of consciousness. Temperature on admission was 98-6°, rose to 99°+ ; pulse, 64 to 128 ; respira- tion, 24. Case XLV1II.—Male, aged twenty-four; fell down stairs; wound over right eye ; haemorrhage from right nostril; coma ; stertor; pupils contracted; temperature, 98'5°; pulse, 120; no paralysis or muscular rigidity ; reflexes normal; fracture of left thigh. Clonic spasm of left side five hours after admission. 28 A CLI.VICO-PATHOLOGICAL STUDY OF Death in ten hours after reception of injury. Hourly tempera- ture, 100°, 101°, 102-4°, 102-4°, 103°, 104-4°, 105°, 106-4°. Thirty minutes post mortem, 108-8°. Case XLIX.—Male, aged four; fell two stories, striking the back of the head; small scalp wound just above external occipital protuberance: large baematoma above each ear; pro- fuse haemorrhage from both ears and mouth and haematemesis ; depressed fracture could be felt beneath the wound ; uncon- scious ; right pupil dilated; neither pupil responsive; slight rigidity of muscles of right side. Temperature, 100-8°; pulse and respiration very rapid ; respiration became Chevne-Stokes. Died in four hours. Case L.—Male, aged fifty-nine; fell twro stories through an elevator and struck his head; contusion about right ear and nose; unconscious for ten days; haemorrhage from right ear and nose and under right conjunctiva; stertor; pupils irregu- lar. At the end of a week restless, and required to be kept in bed by an attendant. Discharge from ear straw-colored. At the end of two weeks patient entirely conscious. Ten days later he walked a little and began to recognize people, and after another ten days he was mentally recovered. Case LI.—Male, aged thirty-three ; thrown from a truck and received a blow upon the head; scalp wound in left tem- poral region ; profuse luemorrhage from left ear; pupils regu- lar. He was semi-comatose, but conscious and rational, next day, and two days later became delirious. Haemorrhage from the ear ceased on the sixth day, delirium continued a week, and vertigo for upward of three weeks. No further symptoms were developed. Case LII.—Male, aged thirty-five; struck on the head by a brick falling eight stories; not made unconscious; compound, comminuted, depressed fracture at right temporo-parietal junc- tion ; squamous portion of temporal much comminuted, and one large fragment driven into the brain; haemorrhage from right ear and nostril; right pupil contracted ; little or no shock. He recovered with some deafness remaining in right ear. Case LIII.—Male, aged thirty-five; fell down stairs while drunk; coma; stertor; haemorrhage from left ear, which con- INJURIES OF THE HEAD. 29 tinued twenty-four hours; pupils contracted. Regained con- sciousness in twelve hours. Five days later, left facial paraly- sis, both upper and lower face involved, and food accumulated between cheek and jaw ; ptosis, etc. No loss of sense of taste. He entirely recovered from paralysis, and suffered only from occasional vertigo. Case LIV.—Male, aged nineteen; thrown from his horse while riding, and struck on the back of his head; contused wound in right occipital region ; profuse haemorrhage from right ear; pupils contracted; unconscious till after his removal to his house, a distance of two miles. He then had severe nausea and vomiting, and was somnolent for several hours. The next morn- ing his pulse and temperature were normal, and he suffered from severe pain in the head, which continued for three days. Iltemorrhage from the ear ceased at the same time. There was no rise at any time in pulse or temperature. At the end of ten days there was*still some pain and tenderness on deep pressure just abvoe and behind the ear. His recovery was complete. Case LV.—Male, aged forty-four; said to have fallen and been struck by a plank; admitted to alcoholic ward, and next day transferred to surgical service when he had partially recov- ered consciousness. The left upper and lower extremities, which had been rigid, had become hemiplegic and anaesthetic. There was an abrasion of the nose, a contusion of the left eye, and a haematoma of the right posterior parietal region. Three days later the left hemiplegia had become complete; movements from the bowels were conscious but involuntary; bladder con- trolled ; temperature, 99°. His mental condition had been un- changed since he recovered consciousness. He answTered ques- tions rationally, and never varied in his explanation of the man- ner in which his injury had been received. He talked con- stantly and rambled in his speech. Upon incision, an open fis- sure was disclosed, which ran obliquely across the right parietal bone, from the anterior superior angle, and into the occipital as far as it could be conveniently traced. There was no depression. A large opening was made through the bone by trephining and use of the rongeur. An epidural clot was found to extend from the coronal suture in front to the superior occipital fossa be- 30 A CLIXICO-PATHOLOGICAL STUDY OF hind, and from the median line to the middle fossa, and was an inch and a half in thickness in its central portions. This clot, when removed, measured four ounces and a half by volume, and left a large cavity, the result of cerebral compression. The dura was apparently uninjured. As haemorrhage was free from some inaccessible point beneath the bone, the cavity was tem- porarily packed with gauze. Two hours after the operation he could move the left leg. Twelve hours later there was sensa- tion in the left arm. The next day sensation was perfect, move- ments of the left arm still restricted, and movements of the bowels occurred which were controlled. Temperature, 98 5°. The second day the brain had regained the volume it had lost by compression, and his mental condition was apparently nor- mal. In four days he was in all respects entirely well, except for his external wound. Case LVI.—Male, aged twenty-three; thrown from his horse and sustained a depressed fracture of the left frontal bone two inches above the orbit. Partial loss of consciousness; haemorrhage from nose and mouth; pupils normal; skin pale and moist, and extremities cold ; two or three hours later pro- jectile vomiting and haematemesis. There was slight ecchymosis of the left upper eyelid before the vomiting; after it both eye- lids became excessively ecchymotic, and at the same time the outer half of the left conjunctiva became filled with blood. The temperature was usually about 99°, never above lOO'b0. He had temporary amblyopia, and no other results followed. Case LVII.—Male, aged forty-five; knocked down and beaten about the head; lacerated scalp wounds in left fronto- parietal region; coma; haemorrhage from both nostrils; pu- pils normal; pulse, 100. He recovered partial consciousness in one hour, and became excessively irritable; full conscious- ness returned next day, and he was removed from the hos- pital. Case LYIII.—Male, aged twenty-six months; fell four stories; extensive scalp wound in right occipital region; re- peated vomiting; haemorrhage from right ear. Three hours later he became restless, had clonic spasms upon the right side, and gradually lost consciousness. There was apparent complete INJURIES OF THE HEAD. 31 right hemiplegia; movements of the left side were easily in- duced ; pulse 130 and weak ; breathing stertorous. Conscious- ness gradually returned within twelve hours, and no paralysis remained. There were no further symptoms. Case LIX.—Male, aged thirty; fell from elevated railroad to sidewalk, striking upon left side of head and face ; contusion over left eye; semi-conscious; haemorrhage from right ear; pulse and respiration slow. The next day patient recovered consciousness enough to discover that he had become blind in the left eye. He responded slowly to questions and slept most of the time. Ophthalmoscopic examination of the left retina was negative. The left pupil would not respond to direct ex- posure to light, but would contract with the other pupil on simultaneous exposure. In the opinion of Dr. P. A. Callan, the blindness was due to pinching of the optic nerve by a fracture involving the optic foramen. Fifteen days later Dr. Callan found commencing atrophy of the optic nerve. Eight days after the injury there was partial left facial paralysis, and the tongue deviated to the right. He complained of pain over the left eye and behind the right ear. A slight sero sanguinolent discharge began to flow from both ears, continued for some days, ceased, and reappeared from the right ear. Temperature on admission was 99°, rose to 100°, and afterward varied, usually from 99° to normal. The patient, a man of unusual intelligence, stated, after bis recovery, that for five weeks after his accident he was unable to recollect the attendant circumstances or anything that hap- pened about that time or afterward ; that bis mental condition was one of great confusion. After that period his memory was restored and his mental confusion disappeared. His recovery was ultimately complete, with the exception of the loss of sight of the left eye. The diagnosis made was: Fracture of the frontal bone, com- mencing on the left side, extending through the anterior fossae and through the right middle fossa and petrous portion, involv- ing the left optic foramen and lacerating the prefrontal lobe. Case LX.—Male, aged forty-seven; was knocked down by a blow and his head struck heavily upon the pavement; slight con- 32 A CLLYICO-PATHOLOGICAL STUDY OF tusion upon lip and over right eye; pulse, 72; temperature, 100‘2°; unconscious; stertor; pupils normal; soon became delirious and was unable to articulate. He remained in a con- dition of stupor and delirium for ten days; required mechanical resraint. He was unable to articulate, and was dysphagic; attempted to drink bis urine. His mental condition and power of articulation then improved for two weeks, though he de- veloped left facial paralysis, involving lower face; dysphagia disappeared. There was then an interval of a few days, when he was irritable, restless, and disposed to wander about the ward at night. His temperature varied from 100° to normal, and was usually at the higher point. From this time he became quiet and conversed intelligently, though his mind wandered. He had no recollection of his injury, of what preceded it, or of anything that occurred afterward. He failed to recognize his location or to appreciate his surroundings. His memory of more distant events was better, but still defective. His laugh was vacant, and there was some perceptible loss of power on the left side. He continued in a demented condition and inci- dentally a dipsomaniac till his removal to an insane asylum within the last month, two years after the injury. Case LXf.—Male, aged twenty-two; fell two stories and struck right side of the head and face and right shoulder; con- tusions of those regions and fracture of acromion; uncon- scious; haemorrhage from right ear, and four hours later from the nose; regained consciousness in five hours; haemorrhage from ear ceased in three days; temperature, 101° to 100°; nor- mal after four days. Case LXII.— aged twenty-two; fell three stories; contusions of right side of head, face, and eye; haemorrhage from right ear and month; unconscious; pulse slow and full (60); breathing labored; temperature, 101°; pupils normal. Respiration soon became easier, but the patient was irritable and restless lie did not regain consciousness for five days, during which time he continued to be irritable when disturbed, and was not wholly rational for five days longer. Toward the end of the second week his articulation became thick and right lower facial paralysis became evident. At the same time a INJURIES OF THE HEAD. 33 swelling without discoloration of the left side of the face, which had been present since admission, perceptibly increased, but soon afterward disappeared. The facial paralysis persisted and the difficulty of articulation increased. His mental condition varied, but progressively deteriorated. There was slowness of perception and hesitation in expression. His laugh was silly and his manner vacant. There also seemed to be a sensory aphasia at a late period. In reply to questioning about the manner of his accident, lie would talk about taking a basket of clams from Koster & Bial’s. He might say “ Koster & Bial’s,” but was quite likely to say “ Koster and clams.” At the begin- ning of the second month there was a sudden change. His mind in a day became clear; he knew where he lived and that he was in a hospital. He conversed rationally about his acci- dent and how it occurred. He lost his delusions and rested quietly at night, though his speech was still a little indistinct and his facial paralysis had not entirely disappeared. Temperature after the third day was rarely above 99° and oftener below it. His recovery was ultimately complete. Case LXIII.—Male, aged forty ; fell five steps of a stairway . walked home; haemorrhage from right ear; had two convul- ions next day and was then taken to the hospital; haemorrhages from the ear still continued; stupid; muttering; two other con- vulsions, most marked on the right side, followed by mild de- lirium through the night. No previous history of epilepsy or excesses in drink. Temperature, 101 ‘2°. Three days later pa- tient was still stupid, said little and that incoherently, and was delirious. Temperature had ranged from 101 *2° to 100 6°. He was transferred to Bellevue, and there became wildly delirious for three days, and then quiet and rational. Temperature, 98'8°. No further history noted ; no other symptoms. Case LXIV.—Male, aged forty-two; cause of injury un- known. Semi-conscious and drunk; haemorrhage from right ear which continued eight days; membrana tympani ruptured ; violent mania for two days and mild delirium two days longer . temperature. 100°. Four days afterward he suffered pain in the head; had Occasional delusions; his mental processes were slow, and his tongue deviated to the right; urine and faeces A CLINICO-PATHOLOGICAL STUDY OF 34 incontinent. In the second week he became rational and only occasionally soiled the bed. His tongue still deviated. At the end of a month he no longer had symptoms; even the deafness had improved. Temperature second day, 103°; gradual de- cline to 99° in four days. After seventh day habitually normal to 99°. Case LXV.— Male, aged forty; fell down a gang plank. Unconscious; haemorrhage from both ears, more from the right; pulse, 100; temperature, 100°. After some hours con- sciousness returned and he was able to speak. Delirious through the night. On the next day his tongue deviated to the right; pu- pils dilated, left more so than the right; mind still clouded; temperature, 99-6°. Four days later he was rational. No fur- ther symptoms. Case LXVI.—Male, aged twenty-three; walked out of a window while sleeping and fell three stories to a stone pave- ment below, striking an iron fence on the way down. He re- mained unconscious for fifteen or twenty minutes. On admis- sion, there was a wound of the external right ear. While this wound was being dressed a very profuse serous discharge began from this ear and continued for several days. Pupils and respi- ration normal; severe vertigo, aggravated on attempting to arise or on opening his eyes; he vomited several times; pulse, 90; temperature, 99°. On the fourth day he had upper and lower incomplete facial paralysis which continued for a week’s time. On the eighth day he had three epileptiform convulsions and one on the next day. The head and eyes were first turned to the right, then the arms and finally the legs were involved. On the twentieth day he began to have severe pain in the right ear, and as the mastoid region later became swollen and inflamed, it was trephined for exploration with negative result. The tem- perature but once exceeded 99°. The mastoid inflammation disappeared at once after trephination. Recovery was com- plete. Case LXVTI.—Male, aged fifteen; kicked in the back of the head by a horse. No apparent external injury; profuse haemor- rhage from right ear; was moaning and restless; became de- lirious after a few hours; afterward irrational and incoherent; INJURIES OF THE HEAD. 35 irritable; temperature, 100°; delirious or irrational for five days; temperature, 100° to 102°; removed from hospital in two weeks; temperature, 99°; still had delusions. Case LXVIII.—Female, aged six; fell two stories to pave- ment ; unconscious; lacerated wound over right eye and haema- toina; .contusion of face; severe hemorrhage from mouth and nose and haamatemesis; subconjunctival, hemorrhage in both eyes; pupils dilated; stertor; respiration frequent; tempera- ture, 99° ; reflexes lost; incontinence of urind and feces ; sur- face irritation caused violent convulsions; initial'symptom in the eyes, continued twenty-four hours; also hemorrhage Iron nose and mouth. After that lime all the symptoms disappeared, and patient was out of bed on the tenth day ; temperature rose in three hours from admission to 103‘2°; fell to 98-6° on the second day. Case LX1X.—Male, aged four; struck by some falling ob- ject; contusions over left frontal and right parietal eminences; heemorrhage from mouth, nose, and both ears, and continued from left ear for five days; unconscious; left pupil dilated; left facial paresis; temperature, 99°; somnolent forty-eight hours, but rational when roused; incontinence of urine and faeces; temperature, 100° on second day and 100 4° on third day; did not get below 100° till tenth day; pulse usually 120; symptoms gradually disappeared. Case LXX.—Male, aged forty; fell one story to pavement, striking back of his head ; scalp wound in right occipital re- gion ; haemorrhage from left ear; left pupil dilated; soon be- came normal; unconscious; partially restored in ambulance; on admission, restless and delirious ; temperature, 99'4° ; pulse, 60 ; respiration rapid ; moved right side only ; incontinence of urine and faeces. Temperature ranged during the first week from 100°+ to 101°; then became 99°+ in the morning, and at end of second week became normal • pulse varied from 62 to 54; required continuous mechanical restraint for four days and at night for one month. His mind underwent the typical changes (see remarks on diagnosis), and became ultimately com- pletely restored. 36 A CLINICO-PATHOLOG1CAL STUDY OF Case LXXI.—Male, aged fifty-two; fell backward and struck back of bis head, at the same time fracturing his left patella. At the hospital to which he was taken his head injury did not attract attention. He was delirious on the second day and had a convulsion on the fifteenth, and his condition was attributed to the alcoholic habit. Six months later the patella was wired for non-union. His muscular rigidity under the anesthetic was notable. His temperature the day following the operation was 99° till one o’clock p. m. Half an hour later and without pre- monition he had an epileptiform convulsion which began in the face and became general, and was followed by wild delirium. He had two other similar convulsions, also followed by wild delirium, and the last by a temperature of 103°. The kidneys acted freely and the urine was normal. The wound of opera- tion was the seat of primary union. The temperature was nor- mal on the next day and so remained for fifteen days. At that time an attempt was made to coapt the fragments of the patella, which he had torn assunder in his convulsions and delirium. This failed and there was some subsequent suppuration which elevated the temperature for the next ten or twelve days to 99° + to 102°. The wound was then healed aud the temperature again became normal. At each dressing great muscular rigidity and tonic spasm had been noted in the affected limb (left). Just one month from the previous attack convulsions recurred and were frequently repeated for thirty-six hours. They were all marked by the same characteristics. Each one was preceded by great restlessness. In about fifteen seconds this was followed by wide dilatation of both pupils. The muscles of the left side of the face began to twitch and the eyes deviated to the left. The muscular spasm extended to the other side of the face, then to the left arm and leg, and finally became general. The whole convulsion lasted about thirty seconds. During the day the de- viation of the left eye became permanent. The tendon reflexes were markedly increased. After the convulsions ceased he be- came delirious and died nine hours later. At the time of the seizure his temperature was 100T°, in twelve hours it became FRACTtr'KES OF THE VERTEX. INJURIES OF TIIE HEAD. 37 102°, in twenty hours 104°, in twenty-four hours 104,8°, and afterward fell to 104°. Necropsy.—The knee joint of operation was found to be free from inflammatory complication, and the wound practically healed. A depression was discovered in the skull just above the external occipital protuberance in the median line. This was confined to the external table and no lesion of the brain ex- isted beneath it. At the opposite extremity, however, of the antero-posterior diameter there was a circular laceration upon the anterior border of the right frontal lobe, and another lacera- tion existed upon the under surface of the left frontal lobe, upon the middle of the second and third orbital convolutions, an inch and a half by an inch in diameter. A still larger laceration of the base, at least three inches and a half by an inch and a half in diameter, existed upon the right temporo-sphenoidal lobe, in- volving a little of the first, and almost the whole of the second and third convolutions. All these lacerations were distinctly limited, softened, and of a brownish color, showing the consid- erable time which had elapsed since they were inflicted. The whole right temporo-sphenoidal lobe was greatly atrophied, in- durated, and pigmented. The pia was thickened over each laceration. Case LXXII.—Male, aged forty ; cause of injury unknown; found unconscious in bed ; contusion of forehead and left upper eyelid ; pupils regular and fixed ; right facial paralysis; both arms and right leg rigid; pulse, 96; respiration, 36. Twenty- four hours later, right arm paralyzed, but still rigid; could not determine whether right leg was paralyzed ; pulseless ; died in thirty hours; temperature at admission, 102‘6°; twenty-four hours later, 105°. Necropsy.—Hematoma over vrhole left parietal region. Lin- ear fracture across whole length of parietal bone just above tem- poral ridge, recurving upon itself posteriorly for a little distance. Large epidural clot beneath the fracture compressing and flatten- ing the whole left hemisphere and forming an oblique plane. General contusion of the whole brain, which was hypersemic and studded with minute extravasations. Case LXXI1I.—Male, aged twenty-eight; received a blow 38 A CLINICO-PATHOLOGICAL STUDY OF upon the head from a falling elevator (lift); compound commi- nuted fracture of right frontal bone; wound filled with clot and brain tissue; opening in the skull an inch and a half by half an inch in diameter. After cleansing the wound a cavity was left in the frontal lobe as large as a Mandarin orange. The patient was semi-conscious, but mental condition soon became normal. Pulse, 68; temperature, lOO^0. Vomited frequently. At the end of twenty-four hours he was rather heavy and somnolent, but could be easily roused, and was rational. Two hours later he was found in a comatose condition, with a temperature of 105’4°, and died soon afterward, twenty-seven hours from the time he received the injury. • Necropsy.—Two large fissures ran backward on either side of the skull, one terminating in the parietal and the other in the occipital bone. There was no epidural haemorrhage. An irregu- larly shaped piece of the internal table was detached and rested upon the brain just above the cavity noted, but nearer the me- dian line, and a subdural clot three inches in diameter and half an inch thick was situated just posterior to it upon the right frontal lobe. There was slight cortical haemorrhage in the left occipital region. There was no lesion at the base. The cavity made by laceration of the frontal lobe extended nearly to the lateral ventricle. The whole brain, including the pons, optic thalami, and corpora striata upon both sides, and the cerebel- lum, was streaked with minute coagula, some of which, an inch in length, could be teased from the vessels. Case LXXIV.—Male, aged thirty-two; fell thirty feet into the hold of a vessel, striking upon his back. Unconscious; pulse and respiration slow ; stertor ; no other symptoms. Condition resembled that of alcoholic coma. Next morning the tempera- ture was 101'6° ; evening, 10P8o. On the second day, a. m., 103’8°; m., 104'2°; p. m., 105‘4°. Right hemiplegia and both eyes turned to the left. Pupils normal. Pulse feeble and rapid. Respiration inadequate from pulmonary oedema. Still uncon- scious. On the third day temperature, a. m., 106'4°. Death in sixty hours. Necropsy.—-Separation of coronary suture from right frontal eminence to its left external extremity. Not much epidural INJURIES OF THE HEAD. 39 haemorrhage. Laceration of posterior extremity of left tem- poro sphenoidal extending into occipital lobe. Consequent subdural haemorrhage of moderate amount, involving left mo- tor area and occipital lobe to the base. Another laceration existed on the posterior border of the left cerebellum. General contusion. Case LXXV.—Male, aged thirty-two; fell from his truck. Contusion of left parietal region ; unconscious ; irritable when disturbed ; temperature, 99° ; pulse, 60 and full; coma con- tinued for about a week with temperature from 99° to 100°, then a period of irritability and mild delirium which lasted two weeks longer. Mental condition after the first two weeks apa- thetic and weak. He answered questions rationally when spoken to, but rambled in his speech. He recognized his friends, but spoke only when spoken to and had some delusions. At the end of a month he was transferred to Mount Sinai Hospital and died there. Necropsy.—Fracture found in left occipito-parietal region. Laceration. Case LXXVI.—Female, aged twenty-three; suicidal gun- shot wound through right temporal fossa; median line of ver- tex presented a conical elevation ; haemorrhage considerable ; patient unconscious with stertor; coma became more profound; temperature fell to 95° ; pulse rapid ; death in four hours. Necropsy.—Scalp infiltrated with blood. Bullet entered frontal bone a little above and external to right eye, penetrated the brain, passed inward, upward, and backward, and impinged upon the inner surface of the skull, a little to the left of the median line in the middle parietal region. It elevated two little triangular pieces of bone which remained attached to the peri- cranium. The bullet then fell back into the brain. It had en- tered at the anterior extremity of the fissure of Sylvius, trav- ersed the right frontal lobe, just below the cortex and parallel to its curve, and then passed a little backward and across the longitudinal fissure below the longitudinal sinus, into the left parietal lobe ; after fracturing the left parietal bone and falling back into its cerebral track as noted, it rested about half an inch below the surface. The skull was very thick and fissured from 40 A CLINICO-PATIIOLOGICAL STUDY OF the point where the bullet entered. There was little intracranial haemorrhage. Case LXXY1I.—Male, aged twenty-six ; homicidal gunshot wound in right temporal fossa; patient unconscious; pupils normal; general muscular twitching; coma became profound, and death followed in twelve hours. Necropsy.—Bullet entered just behind external angular pro- cess of right frontal bone, traversed the right hemisphere nearly in its antero-posterior diameter, just above corpus callosum, im- pinged upon inner surface of the occipital bone, and, rebounding through the opening in the dura, fell into the inferior occipital fossa. Considerable subdural haemorrhage. Case LXXVIII.—Male, aged forty-two; suicidal gunshot wound in right temporal fossa; patient nnconsciouss; pulse, 70; no other symptoms. He soon regained consciousness and was rational, but bis mental processes were sluggish. He had syphilitic laryngitis and aphonia. Temperature, 99°. An at- tempt was made to remove the ball next day, the opening in the bone at about the right temporo-frontal junction having been enlarged by the trephine. The track of the ball could be traced about two inches and a half forward, downward, and in- ward, at which distance a piece of bone, carried inward by the ball, circular and comprising both tables, was discovered and removed. Considerable brain matter oozed out during this ex- ploration. The ball was not found. Xo reaction followed the operation. The patient lived thirty days. His urine and faeces were voided freely, but without attracting his attention. The discharge of brain matter from the wound gradually diminished. At the time of his deatl) the external wound had almost en- tirely healed. The most notable symptom in his condition was hebetude. He remained rational but quiet, listless, and taking no notice of people or things, and without interest in what went on about him, with occasional intervals in which his mind seemed brighter. The temperature ranged from 100° + to 103'6°, and was usually above 101°. Necropsy.—The ball entered the brain about the middle of the third right frontal convolution, and passed nearly trans- versely through the center of both frontal lobes, and lodged INJURIES OF THE HEAD. 41 just behind the ascending arm of the fissure of Sylvius on the left side in the upper portion of the island of Reil. Its track passed just above the anterior horn of both lateral ventricles, and above the corpus callosum, just involving the calloso- margi- nal convolutions. On the left side the track was sharply de- fined, and formed a cavity five eighths by seven eighths of an inch in diameter containing the ball surrounded by clot and brain detritus. This was separated by the median fissure from the cavity on the right side from which the bone was extracted during life. Between the two cavities was a minute piece of bone. Case LXXIX.—Female, aged eight, fell three stories; con- scious; shock; compound comminuted depressed fracture of left frontal bone, with laceration of brain and meninges; rest- less and delirious; died on the third day; temperature on ad- mission, 100*2° ; rose to 104 6°. Necropsy.—Cavity in left prefontal lobe filled with clot and brain detritus. No considerable intracranial haemorrhage. General contusion of brain substance with coagula in minute vessels. Case LXXX.—Male, aged fifty; cause of injury unknown; unconscious; pulse and respiration rapid; temperature, 100°; both pupils dilated; died in four hours. Necropsy.—Simple fracture of left temporal bone, squamous portion. Deep laceration of right temporo-sphenoidal lobe, also of anterior border of left temporo-sphenoidal, smaller and shallower. Whole superior surfaces of both hemispheres cov- ered by cortical haemorrhage. Case LXXXI.— Male, aged sixteen; struck on the head by an iron wrench; scalp wound; depressed fracture at right parieto-occipital junction; trephined and elevated; no general symptoms; walking case; no injury of dura; no subsequent symptoms. Case LXXXIf.—Male, aged thirty; struck on the head; compound depressed fracture of left temporal bone at parietal junction; temporarily unconscious; afterward dazed; agraphia; trephined and bone elevated next day; agraphia continued eight days; sensory aphasia on the third day; temperature on ad- 42 A CLINICO-PATHOLOGICAL STUDY OF mission, 99°; next day, 103°; second day, 103-8°; became nor- mal on eighth day; afterward varied from 99° to 102° for twenty days; did not again become normal till thirtieth day. Case LXXXIII.—Male, aged thirty-three; blow from a cleaver; fragment of outer table of left frontal cut off and left hanging by the periosteum, including the frontal eminence; condition irritable; wound healed in four days; no subsequent symptoms. Case LXXXIY.—Female, aged two years and a half; fell down stairs; compound depressed fracture of left parietal bone just posterior and external to frontal eminence; wound lacer- ated and contused. Three days later, convulsion occurred and admitted to hospital. Wound suppurating and sloughy. Xo general symptoms. Bone elevated. Highest temperature, 102°. Discharged in twenty-eight days; readmitted fourteen days later; subdural abscess; hernia cerebri; abscess in brain evacu- ated ; hernia subsided and patient discharged. Case LXXXV.—Female, aged forty-two; struck with a hammer weighing eight pounds; several lacerated and con- tused wounds of the scalp, and a depressed fracture of the pos- terior inferior part of the right parietal bone one half by three fourths of an inch in diameter, with a fissure running forward; hsematoma over right malar bone and a contusion of the back of the neck; patient conscious, rational, and restless; pulse, 120 and full; temperature, 99°; third day, 100°; fourth day, 104°; trephined and elevated; some epidural clot removed; dura tense and not pulsa'ing, and was incised; small amount of blood and serum escaped; wound healed at once and tem- perature fell gradually to 99° in four days ensuing. Six months later, I was told by Dr. G. Douglass that he had seen her at about that time. She was very nervous, excitable, and com- plained that she was confused and “ wrong in her head ” ever since her discharge. Case LXXXVI.—Male, aged thirty-eight; was struck by a bottle in middle of forehead; he was dazed, but able to walk; compound depressed fracture of right frontal bone extending into orbital plate, and frontal sinus opened; trephined and a piece of bone, an inch and a half square, with a sharp edge, INJURIES OF THE HEAD. 43 which had penetrated the cerebral substance, was removed. The superior longitudinal sinus was torn, and haemorrhage was controlled by pressure against the hone with one blade of a Langenbeck’s forceps. Sutured in position till the third day. The patient for a time was irritable and delirious, requiring me- chanical restraint. The temperature was very uniform, vary- ing only from 99° to 100°, when it became normal. Case LXXXVLI.—Male, aged forty; knocked down by a blow upon the head. When he recovered consciousness he walked into the hospital. Compound depressed fracture posterior to left frontal eminence, and piece of inner table driven in. Dura uninjured. No general symptoms. Temperature, 101° to 102° for six days, wdien it suddenly dropped from 101° to normal. Case LXXXV1II.—Male, aged fourteen; fell two stories; temporarily delirious from fright and excitement, and then recovered and walked home; depressed fracture in right frontal bone near coronal suture; elevated; no subsequent symptoms. Case LXXXIX.—Male, aged thirty; gunshot fracture of right frontal one inch above the zygoma; considerable haemor- rhage from wound and beneath the conjunctiva; right eye pro- truded so much that the lids could not be closed; no mental symptoms; temperature, 99-5° to lOTS0; next day tempera- ture 104°. The bullet-opening in the skull was enlarged by the trephine, several loose pieces of bone removed, and the bullet felt near the optic foramen. The eye was then removed and the bullet extracted through the orbit, the dura having been first incised. The roof of the orbit was found to be much com- minuted. Temperature remained high, and delirium and illu- sions continued for three days. The wound suppurated rather freely for the first month, and the patient often suffered from headache, which was always relieved by changing the dress- ings. He remained in the hospital for two months and was then discharged entirely well. The temperature for the first ten days was 102° to 103° ; for the next twenty days, 100° to 101°; for the next ten days, 100°; and the next ten days, 99° to 99° + .

Case XCIY.—Male, aged sixteen; thrown from a horse; compound depressed fracture of left frontal bone, just above superciliary ridge; conscious and irritable; temperature, 99-8°; pulse, 60, full. A piece of bone, an inch and a quarter by half an inch, completely separated and driven in upon the dura, ele- vated and removed under ether. Had no subsequent general symptoms except temperature, which for ten days was usually from 99° to 100°, and a somewhat irritable mental condition. Case XCV.—Female, aged seven; fell one flight of stairs over the banisters; struck her head ; unconscious; vomited. Became dull and stupid on the second day; next day admitted to hospi- tal. Hasmatoma in left parietal region, and linear fracture, dis- covered by incision, confined to left parietal bone. Tempera- ture, 99°. No subsequent symptoms. CAseXCVI.—Male, aged thirty-two; stabbed in the forehead with a pocket knife. Three days later no general symptoms. Temperature, 99° to 100°; pulse, 76. After incision, the knife blade could be seen broken off at the level of the surface of the bone, an inch and three quarters above left supra orbital ridge, and an inch and a half to left of median line. A button of INJURIES OF THE HEAD. 45 bone, which included the knife point in the center, was removed by the trephine. The point had penetrated the brain a quarter of an inch. Dura incised and closed by suture. No subsequent symptoms. Case XCV1I.—Male, aped twenty ; knocked down by a blow from a heavy stick ; unconscious; linear fracture from just above left superciliary ridge, extending into parietal bone, and incised wound. No general symptoms. Case XCVIII.—Male, aged thirty-one; struck by a shower of bricks; compound depressed fracture of right parietal bone. Trephined, and loose fragment of inner table, half an inch square, removed. No general symptoms. Case XOIX —Male, aged twenty-six ; fell thirty-five feet from a scaffold; had been temporarily unconscious. A frag- ment of the right parietal bone, near its upper posterior angle, including both tables,'had been torn out and was missing, two inches by one inch and three quarters in diameter. The inner table was comminuted, and fragments pressing upon the dura were removed. No fissures. Dura uninjured. No disorders of sensation or other general symptoms. Temperature, 99° to 100° + . Case C.—Female, aged forty-five; fell down stairway at ele- vated railroad station ; unconscious. Admitted after five days. Haematoma over left eye, which had been incised; fissure, ex- tending into frontal sinus, could be detected through the incis- ion. The only general symptom was occipital headache for some days after the injury was received. Case Cl.—Male, aged eight; kicked by a horse; compound depressed fracture of right frontal bone, just above frontal sinus and near the median line. Elevated on the fourth day. Dura uninjured. Opening in the skull which remained was three quarters of an inch in diameter. Had no previous general symptoms. Temperature, from 99° to bh'S0; after the opera- tion, rose in twenty-four hours to 103°, and in forty-eight hours to 104°. In the next five days it fell gradually to 99°, and re- mained 99°-f for ten days following. Once during this time— on the fifteenth day—some serum escaped from the wound at the time of dressing. On the twentieth day some laudable pus 46 A CLINIOO-PATHOLOGICAL STUDY OF escaped, also at the time of dressing, and a probe was carried two inches and a half into the frontal lobe parallel to the orbital plate. The next day the dura was incised to the extent of the cranial opening, and from two to three ounces of laudable pus evacuated. The probe could be carried backward two inches and a half parallel to the cranial wall on the external aspect of the hemisphere, as well as two inches and a half parallel to the orbital plate. The temperature at this time was 99’2° and pulse 96. There were no general symptoms, except a little mental dullness or apathy and slight right lower facial paralysis. His general condition was also becoming asthenic. The cavity was irrigated and drained by tube. Temperature rose next day to 102°+; became normal in a week. Facial paralysis entirely disappeared in ten days. Discharge ceased during the third week. Mental condition became normal, and nutrition rapidly improved after the first few days. There was a fungus, not larger than a hazel-nut, which spontaneously disappeared. The external wound was entirely healed in little more than a month, and no symptoms of any kind remained. INJURIES OF THE ENCEPHALON. Case CIT.—Male, aged forty-one; fell upon his face ; contu- sions most marked on left side of face and eyes; violent deliri- um for two days. Temperature, 103° to 104°. On the sixth day again became delirious, and later unconscious and violently responsive to irritations. Temperature was at no time below 100°, and was 103° just previous to death, which occurred at the end of six days. Necropxy.—Haematoma and small scalp wound in right parie- tal region. Thin cortical coagulum over left occipital lube, ex- tending into median fissure. Subarachnoid serous effusion. Case CIII.—Male, aged sixty ; pushed down three steps of a stairway, and sustained minor superficial injuries. No head symptoms till the fourth day, when he had four convulsions. There was one the next day, and afterward they occurred with increasing frequency till his death on the eighth day. Each one began by twitching of the muscles of the face, with the head and eyes turned to the left, and these extended to the left arm and INJURIES OF TIIE HEAD. 47 finally to the left hand. The right side was not involved at all. Temperature on admission, 100°; in twelve hours, 103°. From this time it varied from 103° to 104° till six hours before his death, when it became and continued 105°. Necropsy.—No lesion of scalp or skull. Subdural haemor- rhage over whole right cerebrum, and extensive laceration of right temporo-sphenoidal lobe. Case CIV.—Male, aged thirty-two ; fell upon the sidewalk ; scalp wound in left occipito-parietal region. Admitted to hos- pital ten hours later. Conscious and rational, but dazed, and with extreme muscular tremor. Two hours afterward the pa- tient had a general convulsion. From this time, during periods of about six hours, there would be a succession of convulsions, with intervals of unconsciousness or delirium, followed by an equal period during which he would remain quiet and rational. The convulsions were all general from beginning to end, without recognizable initial symptom. Died in two days. Necropsy.—Scalp wound, as previously noted. No lesion of skull. Cortical haemorrhage on the right side of the vertex, from anterior border of frontal lobe to posterior fissure of Ro- lando, and covering the temporo sphenoidal lobe laterally and at the base. Deep laceration of right frontal lobe, through the cortex, upon anterior and lateral borders, and extending well into the parietal region. Case CV.—An unknown man was found in the street, lean- ing against a fence in an upright position, dead. Necropsy.—Haetnatoma over right side of the vertex; no lesion of the skull; blood fluid and viscera generally much con- gested ; area of contusion and laceration over greater part ot left frontal and temporo-sphenoidal lobes; subdural haemor- rhage over whole left hemisphere. Case CVI.—Male, aged thirty ; found unconscious and sup- posed to have jumped or fallen from a second-story window. Wound over right eye and fracture of the nasal bones; coma profound; stertor; pupils contracted. On the two following days the temperature rose progressively from 101°+ on admis- sion to 104’5°; pulse full, respiration rapid. Patient could be roused by pressure on supraorbital nerve. On the third day 48 A CLINICO-PATHOLOGICAL STUDY OF still deeper coma, dysphagia, continued irritability, and rest- lessness, and temperature still KM^0. Death at end of four days; temperature, 107*4°. Necropsy.—No lesion of skull; no meningeal lesions; small cortical haemorrhage over posterior part of left parietal lobe, and small laceration of brain at parieto occipital junction; both cerebra hyperaemic. Cask CVII.—Male, aged forty; fell down stairs. Admitted to alcoholic ward and transferred to surgical service next day. Slight scalp wound above right ear; comatose, but later could be roused sufficiently to tell his name; temperature, 103*4°; restless; hypera?sthetic; pneumonia discovered; died next day. Necropsy.—Left lung pneumonic; lower lobe in second stage, upper lobe in first stage; no lesion of the skull; dura mater adherent to the calvarium ; the left hemisphere on its upper surface was completely covered by an organized false membrane, which also dipped into the median fissure and cov- ered its internal surface. This membrane was divisible poste- riorly into two layers; it was thin anteriorly, but fully an eighth of an inch in thickness in its posterior part; its upper surface was smooth, non-adherent, and comparable in appearance to a section.of raw beef; its inferior or cerebral surface was smooth, velvety, non adherent, and could be raised without injuring the arachnoid; it did not dip into the sulci; it was traversed by minute vessels and studded with some fifteen or twenty gray- ish, caseous, and partially calcareous nodules, varying in size from that of a robin-shot to that of a buckshot. Similar nod- ules were found in the basilar vesseb, which were generally atheromatous. No recent lesion of the brain was discovered, except general contusion indicated by moderate hypersemia and some capillary extravasations. His wife subsequently stated that he had never lost a day’s wrork by reason of sickness, and that he had never had even temporary loss of consciousness or paralysis. Case CVIII.—Male, aged titty seven; fell from his cab; unconscious: large haematoma over left parietal region; respira- tion slow and stertorous double facial paralysis and cheeks INJURIES OF THE HEAD. 49 flapping; complete right hemiplegia and anaesthesia; tempera- ture, 99°. Trephined over left motor area; dura pale, teDse, and blQodless; no brain pulsation. After incision of dura, serum escaped freely and the quantity increased when the head was so turned as to drain from the base. No blood clot found. Temperature at time of operation had risep to 103'4° ; six hours later it had fallen to 98‘60. The patient had regained con- sciousness and could articulate, and gave his name and address. Hemiplegia not relieved. After twelve hours, pulsation in the brain returned and he could speak rationally and intelligently, though with difficulty. Two hours later still he had a slight convulsion and death followed in four hours. The temperature remained at 98*6° after the operation for fourteen hours, and it then rose steadily to 104-6° just previous to death. The lower face continued paralyzed and the respiration became frequent and insufficient. Necropsy.—No lesion of skull; laceration of external bor- der of right cerebellum anteriorly, from which clot had formed about circle of Willis upon anterior part of pons and in trans- verse fissure in front of left cerebellum; the vessels were atheromatous; the interior of the left occipital lobe was filled with clot which had completely broken down its structure; the left lateral ventricle was filled with blood which had broken through the saeptum into the right lateral ventricle and also communicated with the blood cavity in the occipital lobe. Case CIX.—Male, aged sixty-three; struck by some part of the machinery of his engine; no general symptoms; tem- perature, 100°; wound in posterior parietal region in median line and curving to the right; contusion over left parietal emi- nence; temperature second day, 103 2°; delirious in the night; temperature third day, lOl’S0 to 101°; headache; fourth and fifth days, temperature, 103'4° to 103°; no general symptoms; sixth day, temperature, lOfi^0, pulse, 140 ; restless and irrita- ble, but rational; weaker; died on the eighth day; tempera- ture last two days from 105° to 105'2o ; post-mortem tempera- ture, 104°. A few hours previous to death there was muscular rigidity of all the extremities, most marked on right side and espe- cially in right arm. There was perforating ulcer of the cornea. 50 A CLINICO-PATHOLOGICAL STUDY OF Necropsy.—No lesion of skull or meninges ; no haemorrhage; no lacerations; cortex of brain and meninges hyperaemic; brain substance moderately cedematous and minute vessels filled with coagula; this condition involved corpora striata, optic thalami, pons, and cerebellum, and was most pronounced on left side and at the base; no minute extravasations; both lateral and both inferior petrosal sinuses were filled with decolorized thx-ombus, extending into jugular vein on the right side; the thrombus was colored only near the torcular Herophili. Case CX.—Male, aged sixty; fell two stories to the side- walk. Contusion of left eye and slight contusion just above it; temperature, 101 4; delirium; pupils and respiration normal; pulse, 114. Later symptoms: patient very irritable; cried out and tried to get away when touched, but replied rationally to ques- tions ; incontinence of urine and fceces; delirium continued; died on the fifteenth day; temperature rose to 103'2° on the fifth day and then fell very gradually to 100°. The day before death it was 103'4°, was lOS^0 five hours ante mortem, and 104’2° one hour post mortem. General symptoms remained unchanged. Necropsy.—No fracture; subarachnoid haemorrhage over both hemispheres, forming a sheet which was thickest about occipito-parietal junction on both sides; some subarachnoid serous effusion in left frontal region; general contusion, which was most marked on left side; hypersemia and punctate haemor- rhages. Case CXI.—Male, aged forty-five; cause of injury un- known ; found unconscious in the street and admitted to hospi- tal after forty-eight hours; contused wound in right parietal region; muttering stupor; rigidity of left arm ; right hemiple- gia, which wras incomplete, but most marked in right arm; pulse, 60; temperature, 101°. On the third day the rigidity of the left arm was increased, and the paralysis of right arm was complete; paralysis of right leg was nearly so; coma absolute ; pulse, 128; temperature, 105°. Trephined over motor area and incised the dura. Pulsation of brain abstnt at first, but soon returned in some degree. His movements became freer, and he began to utter articulate sounds. Signs of sensi- INJURIES OF TIIE HEAD. 51 bility increased; pulse, 108; temperature still 105°. Died next day. Necropsy.—Moderate subacute arachnitis over anterior two thirds of upper surface of right cerebrum; laceration of left temporo-sphenoidal lobe, excavating and tilling with clot its whole interior structure. The haemorrhage extended down- ward around the circle of Willis and upward upon the cere- brum, mainly upon the occipital, but also in patches upon the frontal and parietal lobes. Case CXII.—Male, aged sixty ; found unconscious in bed ; seemed to be in perfect health when lie retired to his room on the previous evening. He was heard moaning; no evidence of injury could be discovered; stertor; pupils normal; rigid- ity of right side; pulse 120 and weak; temperature, 100°. On the next day the right side was less rigid; the second day he was comatose ; temperature, 103'2°, and he died. Necropsy.—No lesion of scalp or skull; large amount of serum under the arachnoid. There was a very soft elliptical area of disintegrated brain tissue an inch and a half by three quarters of an inch in diameter upon the anterior part of the left occipital lobe, near the median fissure. There was a simi- lar area, smaller in size, on the under surface of the same lobe, but with disintegration less advanced, and containing a clot not yet decolorized. There was a red, firm clot beneath the latter and deep in the substance of the cerebellum of more recent formation. The temporal artery was atheromatous, but none of the basilar arteries were diseased. Case CXIII.—Male, aged thirty; fell down stairs; con- sciousness was lost, and only partially .restored. He fell out of bed that night, and again the next day, striking each time upon his right side. Admitted to hospital that evening. No exter- nal evidence of injury except slight contusion over crest of right ilium. Rational, but slow to respond to questions ; left pupil slightly dilated; temperature, 99°. The following day he again fell out of bed, and again the day after, always on the right side, and there was a constant tendency to move to the right side of the bed, which was quite level. Some left paresis and some difficulty in swallowing, which he referred to the left side 52 A CUNICO-PATHOLOGICAL STUDY OF of the throat; transient facial paresis. The amount of paresis and the condition of the left pupil varied from day to day. His mental condition deteriorated; he was stupid, rambling in talk, delirious, apathetic, and had delusions. At first urine, and later faeces, were voided unconsciously. His temperature for ten days was 99°+ ; it then began to rise and was 100°+ to 101°; pulse usually from 84 to 96, and respiration nearly nor- mal. On the fifteenth day he was trephined over the right motor leg area, and a small subcortical cavity discovered, from which half a drachm of yellowish fluid was removed. This fluid was subsequently found to contain numerous leucocytes. There was no marked change in his symptoms after the opera- tion. Temperature was a trifle lower—99° to 100°—till the eleventh day, when it rose to 104°, fell the next day to 100°, and rose again to 104°, when he died from asthenia on the twenty-eighth day after his admission. Necropsy.—Large subarachnoid serous effusion compressing frontal lobes. General cerebral hyperaemia and many minute vessels filled with coagula. The brain substance around the small cavity discovered during life was so'tened, stained a red- dishtgray color, and it contained minute extravasations. Case CX1Y.—Male, aged twenty-nine; was found uncon- scious in Central Park. He was taken to a hospital, sent to court charged with intoxication, and afterward admitted to Bellevue, still unconscious. Small contused wound in right frontal region; pupils slightly dilated; complete left hemiple- gia and hemianaesthesia; slight left facial paralysis; tempera- ture, 106°; pulse, 140; respiration accelerated; convulsions shortly after admission, which were repeated at frequent inter- vals; initial symptom in the mouth and face; arms and legs gradually involved; trephined over junction of right arm and leg areas by house surgeon ; result negative; temperature two hours later, 107’4°, and three hours later still he died in a con- vulsion. The ventricle was aspirated in the operation; tem- perature forty five minutes post mortem, was 109,4°. Necropsy.—Brain and meninges excessively hyperaemic; a small tumor as large as a pea was found in right lower face area; the surrounding brain tissue was disintegrated, forming INJURIES OF THE HEAD. 53 a small cavity; no haemorrhages; the viscera were generally soft and congested. Case CXV.—Male, aged thirty-seven ; was found at the bottom of a stairway with his feet uppermost; unconscious; pupils contracted ; muscular rigidity, especially marked in the legs; pulse rapid; stertor; died in two days without having regained consciousness. Case CXVI.—Male, aged twenty-six; thrown out of a wagon and struck his head; unconscious, but conscious on ad- mission ; contusion in left parietal region; became irritable, and later comatose; died suddenly five hours afterward. Case CXVII.—Male; struck by a cleat falling from aloft aboard ship; large baematoma covering whole right side of the head; unconscious; slight rigidity of left side; pulse full and slow; died in fifteen minutes after admission. Case CXVII I.—Male, aged thirty-two; struck with a shovel; contusion of the right posterior parietal region ; pulse full and slow; temperature, 100°; pain in back of the head; dilatation of left pupil; rigidity of flexor muscles of the arms; somno- lence and restlessness. After twenty-four hours patient be- came stupid and mildly delirious; left pupil widely dilated; urinated unconsciously ; left arm only moved when irritated; sensation slightly more acute on right side; dysphagia marked ; left pupil irresponsive to light. His condition varied from time to time for the first two weeks; left pupil more or less dilated and more or less irresponsive to light; mind obscured and apathetic; some ptosis of left eye. After that time his mind became clear, and he could intelligently describe the manner in which he received his injury. Paralysis of the left external rectus; optic nerve and retina normal; perforation of left tympanum and puriform discharge; some left facial paraly- sis. He was discharged at the end of two months. His ptosis and external strabismus had disappeared, and there was only a perceptible trace of the paralysis of the lower face. His left hemiparesis and anaesthesia were no longer noticeable. He was dull and stupid, which his family said was his normal condition. Case CX1X.—Male, aged twenty five; fell from a truck, striking his forehead; unconscious for twenty-four hours; 54 A CLINICO-PATHOLOGICAL STUDY OF slightly delirious for two days; pain in frontal region after that time; temperature, 100°, followed by mild dementia, which continued till his discharge. Case CXX.—Male, aged twenty-one; fell sixty feet down an embankment; unconscious; afterward, violent delirium lasting a week; then admitted to the hospital, still delirious, but more quiet; suppurating scalp wound external to right frontal emi- nence ; hone exposed ; also double fracture of right inferior maxilla. The following day he had eleven epileptiform con- vulsions within two hours. Each one began with twitching in right hand and arm, extending to left arm and then to both legs, and finally a general convulsion was established. Face not much involved, but eyes deviated to the right. After these at- tacks he remained unconscious for one hour; the right arm was then found to be anaesthetic, and with the right leg paretic. The next day he had one similar attack, but he was more rational afterward and recognized his paretic condition. On the next day he had six convulsions within a little more than two hours, each one beginning on right side of the face and ex- tending to right side of the body before becoming general, and the right arm was paralyzed for five minutes afterward. In the next few hours he had six others, one of which was confined to right side of the face. He was then trephined over left face area and the opening freely enlarged. Dura tense and incised, but no lesion discov- ered. He was then trephined through the exposed bone on the right side without result. No further convulsions occurred. The next day he was entirely rational, and it was discovered that he was aphasic. Some difficulty in articulation previous to the operation was ascribed to the fractures of the jaw. He had both motor and sensory aphasia. Called his own name McNannold. He was discharged at the end of a month. His wounds were entirely healed, right arm still paretic, and mind clear. He had some hesitancy in speech, and the selection of words required a little time. His temperature ranged from 99°4- to 101° during his whole convalescence. Case CXXI.—Male, aged twenty; cause of injury un- known; unconscious for a short time; scalp wound in left INJURIES OF THE HEAD. 55 parietal region near the mesian line, and a large haamatoma just behind it in posterior parietal region. He had no general symptom, except nearly complete paraplegia with flaccid mus- cles and somewhat increased reflexes. There was no evidence of specific disease, and it was possible to verify the fact that no paralysis had existed previous to this recent injury. He was discharged at the end of six weeks and could walk fairly well. The diagnosis was cortical haamorrhage from direct contusion of the brain, extending from left motor leg area acr«*s the median line into the corresponding area on the right side. Case CXXII.—Male, aged twenty-one; cause of injury unknown; found unconscious. Committed as drunk and dis- orderly, and sent to Bellevue as a case of alcoholism. He again became unconscious and was constantly crying out, but always a single phrase. He was restless and hyperaesthetic, and the muscles of both sides were generally rigid. There was a slight scalp wound in right temporal region; incision disclosed no fracture. The day following he was more quiet and the muscles were less rigid. Partial paralysis of the lower left face was developed. He became rational, but apathetic. Then there were two days more of active delirium, after which he again became quiet, but had delusions. He was coherent in speech, though voluble, loquacious, and silly. He had sensory aphasia and agraphia, and his memory of recent events returned; he thought, however, he was born in September, 1891 —two months before. In notation at dictation he interpolated figures, as in writing 495 he wrote 490005. He could write two figures cor- rectly, but not more. After his discharge he returned to the hospital some months later, and was noisy and excitable. Sub- sequent inquiry at the station-house made it probable that he was not intoxicated at the time of his arrest. He remained un- conscious from early evening all night. When he was finally roused he made strenuous efforts to speak. He was only able to say “Peter,” his first name, which he repeated again and again, and evidently strove to give his last name. Tempera- ture, 100-2° on admission ; from 100° to 101° for five days, then normal. After that time averaged 98,5° to 99'5°. 56 A CLINICO-PATHOLOGICAL STUDY OF Case CXX1II.—Male, aged twenty-one; cause of injury un- known ; found unconscious in the street; contusion of left eye and wound over superciliary ridge. On admission, he looked about with a vacant stare, but could not be induced to speak. Next day he had delusions and failed to recognize his family. His subsequent symptoms were all mental. Memory of recent events lapsed. Never spoke except when disturbed, then an- swered questions intelligently but mechanically. For three nights he became violently delirious, and attacked his neighbor in the next bed; then he became quiet again, and began to manifest some interest in what passed about him. Two wreeks from the time of his admission his condition suddenly improved, and he began to remember some things which immediately pre- ceded his injury. For the ensuing two weeks it was mainly noticeable that he never suggested or carried on any sustained conversation, and that he laughed much and without due cause. In the next and final two weeks of his continuance in the hos- pital he ceased to laugh inordinately or causelessly, and his memory seemed to be restored in reference to matters up to the time he was hurt, and since his recovery of consciousness. The only abnormal indication in his appearance was a slightly weak expression in his face. Temperature on admission, 99*2°; after- ward from 99° to 101°. Case CXXIV.—Female, aged seventeen, fell three stories through a hatchway; contusion of left occcipital region; no fissure found on incision. She was unconscious, with muscular rigidity of all the extremities, and was irritable when disturbed. She moved the right arm and left leg only. Temperature, 100'2°. Delirious on the fourth day, and noisy and excitable for several days afterward. There was left paresis and dilata- tion of left pupil on the tenth day, and at the same time incon- tinence of urine and faeces which continued eight days. Tem- perature was 100°+ for the first five days, 99°+ for next five days, and then became normal. It rose on the thirteenth day from 99° to 103-5°, and on the next day to 104'5°. For the next ten days it was usually from 102° to 103°, at which time she was removed from the hospital. She subsequently recovered. She was of bad constitution, had inherited syphilis, was deaf, INJURIES OF THE HEAD. 57 and had interstitial keratitis in both eyes, with loss of sight in one from opacity of cornea. The following cases of idiopathic lesion are added to illustrate simulated traumatism: a. Male, aged fifty five, fell upon the sidewalk, and, after rising and walking a short distance, fell again. Upon admission he had a small wound in the median line of the frontal region. He smelled strongly of spirits and was ascertained to he of intem- perate habits. He was unconscious from the time he fell until he died, seven hours later. He was restless, and upon irrita- tion had muscular spasm of both lower and upper extremi- ties. He had incontinence of urine and faeces, dilated pupils, and Cheyne-Stokes respiration. No paralysis. Temperature, 103-4°, 104°, and 105°. It was subsequently learned that the scalp wound was received two days previously, and that the spirits of which he .smelled so strongly had been spilled upon him in an effort to restore him to consciousness before ad- mission. Necropsy.—Chronic meningitis with great arachnoid opacity but no serous effusion. Basilar arteries extremely atheromatous. Both lateral ventricles enormously distended with very bloody serum. Clot extended through each posterior cornu. The right optic thalamus was swollen with clot which also filled the third ventricle. i. Male, aged seventy-one, said to have accidentally fallen from a chair four days previous to admission ; no loss of con- sciousness ; subsequent delirium ; required mechanical restraint till his death, twenty-four hours later ; pupils contracted ; pos- terior cervical muscles rigid; hyperaesthesia; retention of urine; temperature, 102°, 102° + , 103° ; pulse, 90 to 114. Necropsy.—Abrasion of the nose. Dura mater adherent to the calvarium, and arachnoid to the brain. Little serous effu- sion. Some opacity of the arachnoid. Meningeal and cerebral vessels hyperaemic. Cortex softened. The result of an analysis of the preceding cases may be expressed in a brief 58 A CLINICO-PATHOLOGICAL STUDY OF SUMMARY. I.

Fractures.—It is a noteworthy fact that so many injuries of the head—nearly sixty per cent.—involve fracture at the base. 1 have ranked as basic fractures all those which have involved that region, even though beginning at the vertex, because it is upon the implication of the base that all the so-called characteristic symptoms depend. In fact, frac- tures of the skull which do not begin at the vertex are ex- ceptional. I have found upon necropsic examination but four cases in which fracture at the base was not continuous with a fissure extending from the point upon the vertex at which the violence was inflicted. These four, which began and ended in the base, were evidently from contre-coup. That they were the result of violence acting directly upon the vertex was proved by the history of the injury, as well as by existent wound, contusion, or fracture. In neither one was there the slightest reason to suspect that the force 62 A CLINIC0-PATI10L0GICAL STUDY OF was transmitted through the spinal column. The greater frequency of fractures which extend to the base, when com- pared with those which are confined to the vertex, depends simply upon the fact that, under ordinary circumstances, the physical properties of bone are such that force, even when of crushing character, will not expend itself wholly upon the point of impact, but will extend to a considerable distance. That the fissure extends from vertex to base, and not from base to vertex, is proved, even in the absence of a history, by the mute evidence of the superficial injury, and by the narrowing of the fissure as it passes downward. The ex- planation of the fact that fracture through the middle is more frequent than through the other fossae is equally sim- ple. The experiments of Aran have shown that when any part of the vault is subjected to violence it is the corre- sponding part of the base which suffers. It follows that the central or parietal region is the one most exposed to violence, and it is corroborated by post-mortSm examination. Four cases, aside from those produced by contre-coup, are of special interest simply as fractures. The first is a separation of the temporal bone into its constituent parts— squamous, petrous, and mastoid—in an adult male, the re- sult of an apparently inadequate cause. The specimen was shown to this association two years ago. The second was a comminuted fracture of nearly the whole occipital, the posterior part of, both parietal, and the right temporal bones, in which the fragments were completely detached from each other. This, like the first, was occasioned by a fall in the street, and was accompanied by extensive injuries of the brain, sinuses, and membranes. The patient recovered par- tial consciousness, and lived for a week’s time. The third involved all the fossae on both sides from a fall from the mast-head, and the patient survived two hours. This case I believe to be the first on record in which all the fossae INJURIES OF THE HEAD. 63 were involved in fracture. The fourth case was a wide sepa- ration of the coronal suture on both sides, occurring in an adult without concomitant fracture. The most practical comment to be made upon fractures of the skull is that in themselves they are absolutely un- important. It is only by their 'Complications, immediate or remote, that they involve danger to life. COMPLICATIONS OF FRACTURES. The complications of fracture are haemorrhages, throm- bosis, lacerations, contusions, and paralyses. Their deriva- tives are meningitis, abscess, and atrophy. All of these may be produced directly from injury to the encephalon without fracture, with the exception of one form of haemor- rhage. If epidural haemorrhage ever occurs without the intervention of fracture, I have never seen it in necropsies, or had reason to suspect it in recovering cases. Fractures of the skull without complication are not only without importance or consequences, but they are devoid of symptoms. A simple fissure of the posterior fossa would probably be unsuspected, for symptomatic cervical ecchymo- sis is of the rarest occurrence. A simple fracture of the vault is often overlooked in the absence of pressure symp- toms. In fracture at the base, displacement of the frag- ment does not occur, or is insufficient to occasion trouble, and when the patient survives, union, of course, is without provisional callus. The very general existence of compli- cations, however, often of the gravest character, has given fractuie of the base vicariously both an importance and a symptomatology. The encephalic lesions which complicate fracture include all those which occur independently, and therefore may be considered at once, from a double point of view, as compli- cations and as primary injuries. 64 A CLINICO-PATHOLOGICAL STUDY OF HEMORRHAGES. Epidural haemorrhage is perhaps the most characteristic complication of fractures. In moderate quantity from the osseous or smaller meningeal vessels, it is the usual source of the diagnostic haemorrhages from the ears, nose, or mouth, and into the orbital and subconjunctival tissues. In larger amount and as a source of danger, it is derived from the larger meningeal vessels, notably from the middle meningeal artery. In at least two and possibly four cases it was the immediate cause of death. In a third, involving fracture at the base, life was saved by operation, although the clot removed measured four ounces and a half by vol- ume. Such a case is in evidence that the brain-tissue is really susceptible of compression. Subarachnoid or cortical haemorrhage is ordinarily de- rived from laceration of the cortical substance, and is often the direct cause of death, as well as of certain of the pre- cedent symptoms. From a laceration at the base, whether of the frontal or temporo-sphenoidal lobe, it may cover the whole superior surface of one or both hemispheres, and cause various localizing symptoms which accompany or precede those of fatal pressure. From a laceration of the occipital lobe or cerebellum, it may cause immediate death from compression of the medulla; or the hajmorrhage from the torn vessels of the brain, even in extensive laceration, may be insufficient to seriously modify symptoms or hasten the fatal termination. A moderate amount of cortical haemor- rhage from rupture of the vessels of the pia is also one of the results of meningeal contusion. Subdural hccmorrhage I have found most frequently to depend upon rupture of the arachnoid and escape of blood from the meshes of the pia mater into the arachnoid cavi- ty. In a smaller number of instances its source has been in INJURIES OF THE HEAD. 65 the meningeal vessels. In a recent case there was rupture of the dura mater, and the blood was of epidural origin. Cortical haemorrhage, however, is, of all others, the one most frequently encountered. The majority of lacerations reach the surface of the cortex, and superficial haemorrhage results. THROMBOSIS OF THE SINUSES. The occurrence of thrombi in the sinuses of the dura mater and base of the skull in three cases, under varying circumstances, is not in all of them susceptible of adequate explanation. In the first case, which, like the second, in- volved fracture at the base, the posterior part of the skull was subjected to crushing violence. There was extensive epidural clot, large subdural clot which filled the right in- ferior occipital fossa, and a firm cortical clot beneath the seat of fracture surrounded by an inflammatory exudation. The surface of the posterior part of the right occipital lobe was softened and the seat of minute extravasations. There were small lacerations of the inferior surface of both frontal lobes, and one of considerable size in the right cerebellum, beneath the thickest part of the subdural extravasation. The wall of the posterior part of the superior longitudinal sinus was infiltrated with blood, and the cavity occupied by a thrombus. A second large and partially decomposed thrombus was situated in the torcular Herophili, and ex- tended through the right lateral and petrosal sinuses into the jugular vein. In the second case a simple fissure ex- tended from the right parietal bone into the posterior fossa, terminating in the jugular foramen. There was slight epi- dural and considerable subdural haemorrhage at the origin of the fracture. There were several lacerations in the anterior part of the brain, and on the left side the interior of the tem- poro-sphenoidal and that of the frontal lobe were excavated 66 A CLINICO-PATHOLOGICAL STUDY OF and distended by a clot from a haemorrhage, which had also broken through into the lateral ventricles and occipital lobes and filled them with fluid blood. There was cortical haem- orrhage at the base, which had surrounded the optic chiasm and extended to the anterior border of the pons. The thrombus occupied the torcular Herophili and extended through the lateral and petrosal sinuses into the jugular vein. In the third and final case there wras no fracture, in- tracranial haemorrhage, or laceration. There was, however, general contusion, with moderate oedema and distention of the minute cerebral vessels with coagula. This condition extended to the corpora striata, optic thalami, pons, and cerebellum, and was most pronounced at the base and upon the left side. The thrombus was decolorized, and occupied both lateral and both petrosal sinuses. It extended into the right jugular vein, and was colored only near the tor- cular Herophili. I have detailed all the accompanying le- sions, though I do not believe that they were all related to the formation of the thrombi. In the first case the infil- tration of the wall of the sinus points to its laceration by direct violence as the first step toward the coagulation of its contents. The portion of the sinus in which it began was, moreover, directly beneath the point at which sufficient violence was inflicted to comminute the skull, to rupture its membranes, and to cause localized inflammation in connec- tion with the hsemorhage. The surrounding inflammation might, at first sight, suggest an inflammatory origin, but the absence of inflammatory products in the sinus wall cor- roborates the view I have taken. It is more difficult to ac- count for the thrombus in the second case. There is no positive evidence, but a possible clew exists in the termina- tion of the fissure in the jugular foramen. It may be that some injury done to the vein led to the beginning of throm- bosis at this point. It had no evident relation to the other INJURIES OF THE HEAD. 67 intracranial lesions which can aid in solving the problem. In the third case the thrombus was the only localized le- sion, and again a different and conjectural explanation must be sought. There was general contusion and general throm- bosis of the minute cerebral veins. It is impossible to as- sume either that venous canals of such size should have primarily participated in the effect of a general contusion, or that the obstructing coagula should have extended sec- ondarily into the sinuses. It might more naturally he as- sumed that the thrombus, which was already decolorized, was an antecedent lesion which had led to the venous ob- struction and oedema of the brain tissue. There was, how- ever, no indication of previous disease, and the man was at his work when struck down by the blow which caused his death. These pathologically independent of each other, and may have no significance in symptomatology or treatment. In another case I suspected thrombosis of the internal jugular vein, on account of an oedema of one side of the face and neck, but his recovery precluded a confir- mation of my suspicion. I am unacquainted with any similar instances of trau- matic thrombosis of these sinuses. They were unconnected with pressure or any inflammatory process within or without their walls, or with any dyscrasia of the patient. In the first and second cases I have been able to suggest an expla- nation ; in the third case 1 am still without definite opinion. LACERATIONS. Lacerations and contusions of the brain are unques- tionably first in frequency and importance among all the injuries of the head. They play a part in all fatal cases, and dominate the symptoms in almost all cases of recov- ery. Even when death is the immediate result of haem- orrhage or inflammation, or when, though life be saved, 68 A CLINICO-PATHOLOGICAL STUDY OF the mind is lost, they still ride behind. In every fatal case, with fracture or without, where necropsy has been per- mitted, one at least of these lesions has been found to exist. In every one in which necropsy has been denied, as well as in every case of recovery, the interpretation of symptoms in the light of what has been disclosed by previous post- mortem examination has pointed to the same conditions. They do not occur, however, with equal frequency. While in fifty-eight cases there were forty-eight with lacerations, there were but thirty with marked contusions ; or, different- ly estimated, there were twenty-eight cases of laceration without noticeable contusion, and but ten of contusion without laceration. The lacerations may be single or mul- tiple ; they may be confined to the cortex, or extend a vari- able distance into the subcortical structure ; they may origi- nate subcortically and completely disintegrate the interior of a lobe without encroaching upon the cortex, or they may reach the pia; they may lacerate the pia and rupture the arachnoid, with or without diffusion of haemorrhage, or the membranes may remain intact. In a large proportion of cases the laceration will be with well marked diffusion of haemorrhage. Topographically, there is no lobe or convolu- tion which may not be wounded. It will be seen from the necropsies recorded that the base of the brain, especially upon the frontal and temporo-sphenoidal lobes, suffers most seriously and most frequently, and that the interior of the frontal lobes is oftenest the site of extensive destruction. Several cases will be noted in which the haemorrhage from a lacerated frontal lobe has broken through the lateral ven- tricles into the posterior regions of the brain. I present a specimen of small laceration in almost the exact center of the cerebellum (Case XXXIV). I have no record of lacer- ation of the optic thalami, fornix, velum interpositum, or corpus callosum, though such injuries have been described. INJURIES OF THE HEAD. 69 I also present a specimen of laceration of the pons (Case XXVI). Instances of laceration of the corpora striata and gyrus fornicatus are included in the series (Cases XX, XXIX, XXX, XXXV). The general appearances of these lacerations have been noted by previous writers under the name of contusions, and they require but cursory mention. As they present themselves in the cortex, they are simply lacerated wounds containing more or less coagulum with underlying shreds and granular detritus of brain tissue. After the removal of the coagulum the bottom of the wound is usually pultaceous, and stained with blood or of a grayish color. Sometimes the peripheral brain tissue is softened and dotted with miliary extravasations, and some- times it is of normal consistence and appearance. It is rarely the case that there is not some resulting hajmorrhage which infiltrates the pia, perhaps trivial in amount, perhaps sufficient to thickly cover the base or vertex and the lateral aspects of the brain. The wound may be circular, oval, or irregular in outline, not larger than a pea, or covering the whole extent of the inferior surface of the temporo-sphe- noidal lobe. In case of subcortical laceration the lesion may be a simple extravasation of blood into the deeper brain tissue, as small as in the specimens from the pons and central cerebellum which I have just exhibited, and either as harmless as it is trivial in extent or of deadly im- port. In another instance, as in more than one of the ne- crologies which I have just recorded, the whole internal structure of both frontal lobes may be disintegrated and destroyed; and when the clot and mangled brain have been turned out, nothing but the cortical shell remains. The subsequent changes which these wounds undergo are not numerous. If of considerable size, death ensues in the majority of cases before sufficient time has elapsed to permit any change of importance. The end to be hoped 70 A CLINICO-PATHOLOGICAL STUDY OF for, as in any wound with loss of tissue, is cicatrization. In an experience in the dead-house lasting over many years, it has not been my fortune to meet with an instance of such reparative process, yet I have seen many cases of recov- ery where I am positive laceration had existed. There is a remarkable illustrative specimen in the Museum of St. George’s Hospital, quoted by Mr. Hewitt, in which two large lacerations of the cerebrum, occurring without frac- ture, had cicatrized after many years. The cerebral surface was excavated and the pia and arachnoid were carried over the depression, leaving a cavity tilled with loose areolar tis- sue and serum. The man’s intellect had been clear, and he had suffered no cerebral symptoms. If the patient survives, the process of reparation is evi- dently slow. In certain cases in which old lacerations were discovered after death from more recent injury, there was no contraction of the wounds and no inflammatory changes of importance had begun. The edges of the wounds were slightly rounded, and the coagula which they contained were softened and their color had become rusty or yellow. In necropsic cases of recent laceration an interval of from a few moments to one day, or several, has probably elapsed. The appearances are practically the same what- ever the interval may have been. There is no tendency to meningeal or visceral inflammation in any cases which I have observed, with the exception of the occasional forma- tion of abscess from subcortical laceration. As in the case of general contusion, with profuse oedema and death after fifteen days, no inflammatory changes have been discovered even upon careful microscopical examination. In an ex- ceptional case (Case VII) the temporo-sphenoidal lobe had been seriously lacerated, and after the lapse of six months was the seat of interstitial inflammation and atrophy. INJURIES OF THE HEAD. 71 CONTUSION. Contusion may be regarded as occurring in three forms —general and limited, atfecting the brain, and meningeal, involving the membranes. The limited form may be either cortical or subcortical. Any two or all three of these may coexist in the same case. Limited contusion of the brain differs from laceration as a contusion elsewhere differs from a wound. There is no palpable solution of continuity in the brain fibers, and consequently the hamiorrliagic extravasation can only be minute in quantity and of punctate or miliary form. In reparation only absorption, not cicatrization, is required, and recovery should occur in the major and not, as in laceration, in the minor proportion of cases. It is there- fore less frequently met with in post-mortem observations. As in cortical or subcortical laceration, either form of lim- ited contusion occasionally results in abscess. In the sub- cortical forms it may be difficult or impossible to determine which one of the two is the responsible lesion. I have very carefully described such an abscess in a case reported in the New York Medical Journal, March 19, 1890, and in- cluded in the present series. This abscess, which compli- cated fracture at the base, and two others complicating compound fracture of the vertex, comprise the small pro- portion of cases which represents the danger of this form of inflammation. In the case first mentioned, though frac- ture at the base existed and made it technically one of that class, there was also compound fracture of the vertex in connection with which the abscess was formed. So we may properly consider all the abscesses as complicating the latter form of fracture. In all three cases the dura was carefully examined at the time of accident and found to be unin- jured, and after an interval of more than two weeks with- 72 A CLINICO-PATIIOLOGICAU STUDY OF out the occurrence of meningeal inflammation, the abscess was developed. In each the external wound had been healthy and had nearly closed. These data seem to prove that suppurative inflammation of the brain substance is the result of primary injury of the brain itself, and not second- ary to meningeal inflammation extended from the point of fracture. The time for cortical and meningeal suppurations passed with the coming of aseptic methods, and at the same time hernia cerebri practically disappeared from the field of surgery. These cases, however, show that com- pound fractures still sustain a relation to deep abscess. It is not dependent upon the extent of the attendant lacera- tion or contusion, for that is likely to be as great under other circumstances. It is more probably due to exposure, for, though uninjured, the dura and cortex may not be im- pervious to atmospheric influences. The explanation of this subcortical suppuration is, at all events, neither more nor less difficult than that of subcutaneous suppuration upon the surface of the body. The dogmatic assertion that traumatic abscess of the brain never occurs except there has been wound of the scalp or fracture of the skull is erroneous. Though the cases which I record here con- form to this proposition, I am cognizant of at least two cases which do not. One was a small parietal abscess which I saw some years ago; the other an abscess of enor- mous size in the frontal lobe from a blow received in the ball-field, without the occurrence of superficial injury of any sort beyond moderate contusion. The latter specimen is still in the Museum of the Carnegie Laboratory. The im- portant fact in connection with cerebral abscess at the pres- ent day is that it occurs from direct brain lesion independ- ent of injuries of the scalp, skull, or meninges. General contusion of the brain is more frequent than the limited form, but much less frequent than laceration. INJURIES OF TIIE HEAD. 73 I am accustomed to recognize it in three post-mortem con- ditions : General hyperaemia, with or without oedema, punctate or miliary haemorrhages, and thrombosis of the minute cerebral vessels. They occur separately or together. Examples of each are afforded by the necropsies I have described, and the appearances they present are sufficiently indicated in the enumeration of post-rriortem conditions which I have made. I will only refer to two very recent cases (Cases XXXIII and XXXIV) as well-marked instances of excessive general hyperaemia from general contusion ac- companying laceration, and to one other (Case XXIV) in which death was due to general contusion with oedema. The very moderate hyperaemia which often exists in connection with other lesions I have not specially considered, though it may be of serious importance. Meningeal contusion, as a distinct complication, occa- sions haemorrhage and inflammation. Its relation to gen- eral contusion of the brain is not closely defined. The two conditions occur together or separately, and severity of one when they are coincident is not always proportionate to that of the other. I may instance as illustrative of this uncertain relation two cases—the one of oedema to which I but just now referred, in which the brain tissue was sod- den and the ventricles distended with serum, while the meningeal vessels were hut slightly congested and the sub- arachnoid spaces notably dry; the other, my single case of acute arachnitis to which I shall refer later, in which the whole subcortical tissue was very markedly hyperaemic and the smaller vessels filled with coagula. I do not regard simple meningeal hyperaemia as other than a factor in the more important lesion of laceration or general contusion, with which it may happen to be associated. Haemorrhage is of frequent occurrence. The vessels of the pia are ruptured and the blood is effused ordinarily in 74 A CLINICO-PATHOLOGICAL STUDY OF a rather thin sheet over one or both hemispheres, but may present itself in patches scattered over any part of the brain. When the haemorrhage is more profuse and the clot thicker, it can probably be traced to its source in a cortical laceration. The coexistence of both forms of cor- tical haemorrhage is not infrequent. If the fact be fully recognized that cortical haemorrhages of traumatic origin, unconnected with cortical laceration and without fracture as well as with it, are the result of meningeal contusion, the subject will not require further comment. Traumatic arachnitis, so far as these records show, does not result from direct injury transmitted through fracture of the skull, nor from an inflammatory process propagated from a cortical laceration. This complication was once supposed to be the great danger to be feared from injuries of the head, and when death ensued it was always charged with the fatal result. An examination of the fifty-eight post-mortem observations I have made dis- closes only seven cases in which it was possibly present, and only five in which it was positively determined. Two of these occurred in connection with fractures at the base, and the remainder in simple injuries of the brain in which no fracture existed. One of the former was an acute arachnitis; the other six were characterized by a subarach- noid serous effusion. They all negative the theory of di- rect violence, or of an extension of a prior inflammatory process. The acute arachnitis (Case XVIII) was localized in the right and left occipital regions, while the attendant fracture and subcortical lesion were in the parietal region of one side, and separated from it by an interval in which there was no purulent effusion. General contusion was also present. In the case of subacute arachnitis which complicated a fracture at the base (Case IV), the depressed portion of the fracture which was in the vertex was con- INJURIES OF THE HEAD. 75 fined to the external table, the local lesion was subcortical, and there was evidence of general contusion. In the five other cases, in which there was more or less evidence of subacute arachnitis, there was no fracture at all; in three there was no laceration, but general contusion or cortical haemorrhage from meningeal contusion; in one of the other two the subarachnoid effusion was localized on the opposite side of the brain from the site of the laceration ; and in the other and last of the series the lacerations were old and considerably antedated the immediate cause of death. There can be no doubt that all of these were the result of meningeal contusion. Paralysis.—Another complication which has been sup- posed to be a direct result of fracture is paralysis from bony compression of the cranial nerves. This condition is represented in a single case. In this there was compres- sion of the optic nerve. There was fracture extending through both anterior fossae, involving the left optic fora- men, and pinching the optic nerve at that point (Case LIX). Loss of sight was immediate, and ophthalmic examination showed the condition of the nerve and eye to be normal. Subsequent examinations discovered progressive atrophy. The patient recovered, but loss of sight was permanent. In other cases in which loss of function occurred in parts to which cranial nerves are distributed, as elucidated by post-mortem examination, the cause was found to exist in lesion of the cortical centers or in compression of the nerve by blood effused into its intra-osseous canal of exit. There is so little displacement in fracture of the base that such instances as the one detailed are probably of great infre- quency. CONTRE-COUP. I have called attention to the fact that fractures are usually the result of direct violence, expending its force 76 A CLINICO-PATHOLOGICAL STUDY OF upon the vertex or transmitted in continuity to the base, and that fractures by contre-coup are exceptional. Lacera- tions and contusions of the brain, on the contrary, are al- most invariably produced, either wholly or in part, in this way. In the minority of cases in which some encephalic lesion exists directly beneath the point at which violence has been inflicted, there has usually been further and more serious damage done to the brain in some distant part. There has been either laceration or general contusion dis- covered in each case subjected to post-mortem examination. If the cases of gunshot laceration are excluded, and also those of general contusion in which a question might arise as to the kind of violence to which the lesion should be ascribed, there are only five instances in which the violence inflicted was exclusively direct. It is almost safe, therefore, to assume in any given case that if a lesion of the brain exists, it has been produced by contre-coup at a distance from the seat of direct injury. A careful examination of the cases cited shows this distant point to be almost always upon the opposite side of the brain, and confirms all pre- vious observations that it is likely to be at the base in the middle or anterior lobe. The reasons which have been ad- duced to explain the frequent occurrence of brain injury by contre-coup and its seat by preference have no relation to these necropsies and need not engage our consideration. CONCUSSION AND COMPRESSION. All traumatisms involving brain symptoms were for many years classified as cases of concussion or compression. The classification was undoubtedly simple and of easy compre- hension. If the intracranial space was diminished by the intrusion of bone, serum, extravasated blood, or pus, it was compression. Otherwise all symptoms were referred to a hypothetical vibration of the brain within the skull, a merely INJURIES OF THE HEAD. 77 functional disorder produced by violence. Twenty years ago Mr. Prescott Hewitt described several forms of contusion, in which he included lacerations, and questioned the occur- rence of concussion as a distinctively pathological condition without the existence of anatomical change. Previous to this time several observers had noted structural changes in certain fatal cases, but had not regarded them as either necessary or invariable. Some years later von Bergmann, in a clinical lecture, admitted the existence of botli concussion and compression, with an aetiological difference, and in- sisted upon their clinical identity. He attributed concus- sion to a direct injury from a single impulse, modified by the elasticity of the skull, by which the brain suffered a diffuse disturbance of nutrition without appreciable lesion, lie considered it a suspension of cortical activity followed by a stimulation, and eventually by a depression of the medulla. He recognized it as occurring in three degrees: 1. Involving paralysis of the cortex only. 2. Paralysis of the cortex and stimulation of the medulla. 3. Paralysis of both cortex and medulla, with brief and unobserved medullary stimulation. Cortical paralysis was indicated by unconsciousness; medullary stimulation by slowness of pulse and increase of arterial tension; and medullary paralysis by rapidity of pulse and decreased arterial tension. In compression, he regarded the brain condition as being identically the same, and as manifested by the same-symp- toms, but due to change of cranial capacity and not, as in concussion, to change of cranial form. Finally, he con- sidered diagnosis as only possible by the duration of the symptoms. This clinical lecture was admirably translated by Dr. John C. Schapps, late house surgeon at St. Vincent’s Hospital, and appeared in the Annals of Surgery in 1882. The views of von Bergmann, of which I have presented a resume, are of great weight and authority, and probably 78 A C’LINICO-PATHOLOGICAL STUDY OF represent the cumulation of thought and observation up to that time. I do not know that very much of importance has been added since. I am quite in accord with his opin- ion that concussion and compression should be regarded as one, but would gb further, and, having consolidated the two, would abolish them both together, so far as they are terms used to express a pathological condition. The diffi- culty with all explanations of concussion is that, of neces- sity, they are largely theoretical. To account conclusively for unseen pathological changes, or to authoritatively deny their existence, requires that the syllogism be very care- fully constructed. In this instance, in every fatal case where the clinical history has corresponded to that of re- covering cases a carefully conducted necropsy has revealed organic lesion. In all cases that have been cited to prove that no post-mortem lesion exists not one has been ob- served with sufficient exactitude to make it of the slightest statistical value. There is nothing in analogy to warrant at the present time the assumption that any fatal disorder terminates without involving structural change. Even dis- orders of the nervous system, long considered functional, have with closer investigation fallen more and more into line with organic diseases. It is tenable ground, therefore, to hold from both negative and positive post-mortem ob- servation, as well as from general analogy, that brain injury produces structural change with the same certainty that it occasions palpable symptoms. If the terms concussion and compression be used to indicate a group of symptoms, or a variation of pathological condition, it is objectionable, both on the score of propriety and as being likely to lead to er- roneous diagnosis. If they be discarded, the form of injury the patient has suffered in a given case—as lacera- tion, general contusion, or fracture with haemorrhage—is more likely to be accurately determined than if attention IXJURIES OF THE HEAD. 79 be directed solely to a symptomatic condition that may not clearly exist. If unconsciousness and variation of pulse be accepted as the sole pathognomonic and invariable condi- tions of traumatism, there will still remain many cases of uncertain status. Examples may be cited from the forego- ing necrologies in which, from the earliest moment at which the patient could be reached, there was neither unconscious- ness nor a typical variation of pulse. There can be no doubt, however, that unconsciousness is one of the earliest and most constant symptoms of serious brain injury. The opinion that consciousness resides in the cortex as a whole, and that unconsciousness is paralytic or inhibitory, is con- firmed by the negative results of physiological experiment and by the artificial production of cerebral anaemia. It may properly be regarded, therefore, as symptomatic of brain injury with diffuse effect, but not necessarily of dif- fuse injury. The primary retardation and subsequent ac- celeration of the pulse which have been experimentally proved to be attributable to medullary lesion are not as constant, and consequently of less symptomatic importance. In a majority of cases, at the first moment assistance can be rendered, the pulse is accelerated as it would be in serious injury of other parts of the body. The ambulance serv ice is exceedingly rapid, so that if the retardation of the pulse is so evanescent as a symptom, it has no great practi- cal diagnostic value. The temperature, which has not heretofore received at- tention as an important factor in the genesis of symptoms or in the diagnosis and prognosis of brain injuries, seems to me of primary importance. Analysis of the temperatures which have been recorded in these histories confirms the impression which I formed early in my study of these cases—that an elevation of tem- perature was an early, continuous, and very constant symp- 80 A CLIXICO-PATHOLOGICAL STUDY OF tom in all classes of head injury. I have a record of tem- peratures in 45 cases in which the diagnosis was confirmed by necropsy as well as in 10 other fatal cases and in 28 cases of recovery, a total of 83 out of 124 altogether. I think there can he no doubt of the propriety of including the cases of death without necropsy and the recoveries, since the diagnosis was in each well established. I have a defi- nite recollection that in a considerable number of other cases in which the temperature was carefully observed and recorded, but in which the charts were unfortunately lost, that the averages were not essentially different. Four cases, which proved to be fatal, were admitted with subnormal temperatures—from 94° to 98°. In two a subsequent rise in temperature was immediate, continu- ous, and very considerable ; in the other two death ensued in a few hours without reaction—in all the pulse indicated medullary paralysis, and the lesions were afterward found to be extensive and severe. In six other cases the patient was not admitted to a surgical ward till the second day or later after the reception of the injury, so that the first tem- perature taken chuld not be considered primary, but in each case it was then notably elevated—from 101° to 104‘8°. In one recovering case of fracture of the base with epidural hiemorrhage it was normal, and never exceeded 99°. In the remaining seventy-two cases, without excep- tion, the temperature on admission was above normal. In the majority it exceeded 100°, and ranged all the way from 98‘8° to 106°. It would be difficult to trace a relationship between the character or location of the lesion and the comparative elevation of temperature. The increase was usually progressive, without much recession, and the maxi- mum was reached just before death and sometimes after- ward. The highest temperatures attained were 109° in one case, 108° in one, 107°+ in eight, 106o-f- in ten, and 105°-(- INJURIES OF THE HEAD. 81 in nine, or in twenty-eight cases it was above 105°. In eleven other cases it ranged from 104°-f- to 103°-(-. In three cases the post-mortem temperature was 108'8°, 109°, lCffi^0. Sufficient data have been given to show that in probably no condition, except insolation, is the temperature so uniformly high as in cases of encephalic lesion. Unconsciousness as an early symptom sometimes fails without apparent explanation in cases in which brain injury is undoubted. A variation of temperature, therefore, is the one invariable symptom, and if the patient has rallied from immediate shock, it is always an elevation. Perhaps, like the retardation of the pulse, depression of temperature may always be the primary change, but, if so, like the primary pulse change, it is too evanescent to be practically diag- nostic. In many trivial head injuries elevation of tem- perature is absolutely the only symptom ever recognized. The symptoms should be rated in order of constancy, ele- vation of temperature, unconsciousness, and acceleration of pulse. Since this elevation of temperature is a constant phe- nomenon, whatever the nature of the lesion or wherever situated, it would seem to be due to an affection of the cor- tex as a whole, and not to special lesions of localized heat centers. To this extent it might be comparable to experi- mental results in the attempt to discover cortical centers for organic functions. To what degree and in what man- ner the demonstrated heat centers are implicated in the general cortical change is not within the scope of this paper to discuss, nor within my province or competency to deter- mine. The primary effect of brain injuries may therefore still be attributed to an affection of the cortex in its totality, in accordance with von Bergmann’s view, but manifested by two symptoms in place of one—an invariable variation in 82 A CLINICO-PATHOLOGICAL STUDY OF temperature and a nearly invariable loss of consciousness. There is no reason to doubt that the medulla is next in- volved, and the effect of its stimulation and subsequent paralysis have been too thoroughly demonstrated to admit of question. The diagnostic value of the symptoms it affords, however, has not been apparent in these histories. I have not quoted the pulse records, because they have not been sufficiently characteristic to justify the necessary ex- penditure of time and labor. The post-mortem observations disclose in every instance gross lesions in one or more regions of the brain or its membranes, which give a material basis for the symptoms which preceded death, whatever may have been the in- tervening processes which connected the structural change with its outward manifestations. It is for this reason that I would exclude the terms concussion and compression from systems of classification and descriptive histories of cases. SYMPTO MATOLOGY. The symptoms of injuries of the head, excluding those which are casual and without diagnostic significance, are fairly numerous. Fracture at the base has two symptoms peculiar to itself, and fracture of the vertex has also two ; the others are common to both forms of fracture and to purely encephalic injuries. Those peculiar to fracture at the base are serous discharges from the ears or nose, and haemorrhages from the ears, nose, or mouth, and into the orbital, subconjunctival, or cervical subcutaneous tissue. The characteristic symptom of fracture of the vertex, aside from a possible local serous discharge, lies in its perception by sight or touch. The symptoms of encephalic injuries, as a class, whether they occur independently or as complica- tions of fracture, are superficial injuries; peculiarities of temperature, pulse, and respiration; unconsciousness; de- INJURIES OF THE HEAD. 83 lirium ; irritability ; paralysis ; muscular rigidity ; convul- sions ; anaesthesia and hvperaesthesia ; pupillary changes ; and, in a late stage, dementia. Other symptoms, as cepha- lalgia, vomiting, vertigo, incontinence of urine and faeces, are frequent, but of lesser clinical value. The haemorrhages, serous discharges, and visual or tac- tile detection of fracture are pathognomonic. The haemor- rhages occurred in twenty cases and the serous discharge in one, and the necropsy in each confirmed the indication the symptom had afforded. In the fourteen cases in which they were absent, the line of fracture in each was found to he such as to preclude the escape of blood during life through any of the recognized channels. The direct evi- dence of fractured vertex was present in five cases, includ- ing three of gunshot wound. There were simple contusions, large haematoma, or wounds, perceptible in fifty out of the fifty-eight cases. These superficial injuries were of great importance, not only by affording positive proof that violence had been suf- fered in cases where unconsciousness of the patient and absence of history rendered such confirmation essential, but by indicating the point at which it had been inflicted. Sufficient has been said of variations of pulse and tem- perature and of unconsciousness, and little need be added in regard to peculiarities of respiration. In the majority of cases it was simply rapid or normal, and the chart rec- ords have not been transcribed for the same reason that they were omitted in case of the pulse. It was occasion- ally slow, in some instances not more than seven or eight in the minute, sometimes irregular or stertorous, sometimes of the Cheyne-Stokes variety, and in two or three instances dependent in character upon the presence of pulmonary oedema. As in case of the pulse symptoms, I have been struck by the habitual absence of distinctive respiratory in- 84 A CLINICO-PATIIOLOGIOAL STUDY OF dications of medullary implication in serious cortical dis- turbances. Delirium, or some form of mental impairment, is of rather frequent occurrence. It sometimes replaces uncon- sciousness as the earliest noticeable symptom, and some- times appears as a much later manifestation. It may be violent and simulate alcoholic mania, or it may be mild and coexist with stupor. The most characteristic form of men- tal disorder which I have encountered in cases of head in- jury is that of nocturnal delirium, with more or less mental disturbance by day, and in time lapsing into permanent de- mentia as a termination, or sequel, of the traumatic lesion. It may follow at once upon recovery of consciousness, or it may succeed active delirium. At night the patient often requires mechanical restraint, while during the day he an- swers questions intelligently, is coherent in his speech, and may appear entirely rational. His memory, however, is de- fective, or wanting altogether, in regard to all the circum- stances attending his injury. He has delusions and fails to recognize his surroundings. He is prone to drink his urine, and is often apathetic. His mind may finally become clear, his memory of lost events return, and his mental recovery be complete. In other cases his condition becomes one of dementia and some degree of mental impairment is perma- nent. Such a condition as 1 have described I presume is not novel to the alienist, but I note it as a special charac- teristic of injuries of the brain substance, not as a sequel, but as a symptomatic condition of recent lesion. Another allied symptom is the sensitiveness to external irritations in cortical lesions. It seems to be not only a hyperanajsthesia of the cutaneous surfaces, but also a marked mental irritability. There is not only exaggerated muscular movement from slight irritations and disturb- ances, but the patient manifests great vexation and impa- INJURIES OF THE HEAD. 85 tience, though apparently unconscious. It is not usually followed by muscular spasm. Convulsions, muscular rigidity, and muscular tremor may also be classed as irritative symptoms. The first and second occur in a considerable number of cases, a majority of which prove fatal, and upon necropsic examination dis- close haemorrhages and extensive lacerations and possibly general contusion. In the case of atrophy of the temporo- splienoidal lobe, already described, convulsions were exceed- ingly severe; but they followed operation, and a single one occurred fifteen days after the original injury, so that it is by no means certain that there was any aetiological connec- tion between the lesion and the symptom. It is fair to as- sume that they are always evidence of serious lesion, even when recovery follows. The few instances of muscular tremor were in men addicted to drink, but not intoxicated, and who died from the effects of extensive structural changes. Paralysis and anaesthesia, general and local, are recog- nized indications of traumatic, not less than of iodiopathic, affections of the encephalon. In the present series of cases they have occurred perhaps oftener than indicated in the histories, since in so many instances consciousness never returned. In this condition paralysis of the extremities and certain of the local paralyses—facial, ocular, or even glosso-pliaryngeal—can be recognized; but many others, as well as sensory disturbances, remain hidden. The multi- plicity of lesions, which is the rule rather than the excep- tion, is confusing. In testing cutaneous sensibility the re- sults are sufficiently contradictory and unsatisfactory even under more favorable conditions. Yet, despite all these dif- ficulties, in two cases of lesion of the gyrus fornicatus the observations were productive of some result. In three cases of conjugate deviation, the necropsies afforded more 86 A CLLVICO-PATHOLOGICAL STUDY OF or less satisfaction according to the view taken of the loca- tion of the cerebral center. In a general way, however, while traumatisms may in some instances be of service in the solution of various unsettled questions in cerebral local- ization, such cases will probably continue to be exceptional. The fact that defined lacerations are so largely situated at the base of the brain, out of the region in which functional areas have been located, still further diminishes the chances that traumatism will aid much in perfecting cerebral to- pography. It is none the less important, in all cases of profound unconsciousness, to examine critically for such forms of paralysis as are undoubtedly recognizable as well as for those the discovery of which is likely to be more problematical. Pupillary changes are valuable positive evidence of or- ganic injuries, but are less important as negative signs. In a minority of fatal, as well as of recovering cases, I have found the pupils to be abnormal, either variable, unsym- metrical, dilated, or contracted. Unilateral dilatation is probably the most frequent deviation from the normal con- dition, and is likely to be associated with other and more decisive symptoms. I shall not stop to consider casual or remote general symptoms, though, in connection with others more charac- teristic, they sometimes acquire a value which is not in- trinsic. Vomiting and incontinence of urine and fajees are among the most constant symptoms encountered in head injuries; but the one is not less frequent in peritonitis and pregnancy, and tjie other is quite as common in a great variety of functional and organic disorders of the brain which have no relation to traumatism. There can be no doubt, however, of the value of such indications when they occur under circumstances which render traumatism prob- able, either by the history or by the concurrence of more INJURIES OF TIIE HEAD. 87 directly suggestive symptoms. In the same connection occipital headache might he mentioned as so general in re- covering cases of fracture of the base with epidural haemor- rhage as to assume almost diagnostic importance. I have not specifically noted in the various cases the symptoms which were not manifested, but with the excep- tion of temperatures, when unmentioned, they may be re- garded as absent. The results of head injuries have been sufficiently indi- cated as recovery, death, and dementia. DIAGrNOSIS. The diagnosis of injuries of the head as a class is al- ways of interest, is usually practicable, and under some circumstances is one of the most important in the domain of surgery. Grievous error has entailed equal disgrace upon the surgeon and suffering upon the patient. These lesions are first to be distinguished from all other morbid conditions, especially from those involving loss of con- sciousness or delirium, and, secondly, they are to be dis- criminated from each other. It is unnecessary to enumer- ate or consider all those diseases which may simulate their symptoms. The one of primary and paramount importance, and which demands most earnest and careful attention, is the coma produced by alcohol. Its importance can not be overestimated, not only because it is the one with which the condition of traumatic coma is most likely to be con- founded, but because error in diagnosis inflicts so much unnecessary suffering, additional danger, and possible dis- grace upon the patient, while it places the most serious re- sponsibility upon the surgeon. The number of instances in which injuries of the brain have been mistaken for alco- holic coma and the patient left to die in the cells of a police station, or committed to the alcoholic ward at Belle- 88 A CLINIC0-PATI10LOGICAL STUDY OF vue, or even sent from a police court to a term of impris- onment, is inexcusably great. A large proportion of such cases which came into my service at Bellevue, previous to the past year, were transferred from the alcoholic ward. It is a pleasure to acknowledge that within the year great progress has been made in the acquisition of knowledge among those who render first aid to the injured, even to the extent of realizing that an unconscious man with a scalp wound is not necessarily drunk, and that even a drunken man may be so seriously injured as to require hospital treatment. Unconsciousness and the existence of superficial injury of the head should in any case arrest at- tention and awaken suspicion of brain lesion. Coma ought not to be ascribed to alcohol, except by the strictest pro- cess of exclusion. Symptoms which are most likely to characterize different forms of head injury should be sought seriatim. It should be remembered, finally, that, even if the patient be intoxicated, this circumstance should strengthen rather than allay suspicion of traumatism. I believe the temperature affords the means of absolute diag- nosis. I have shown, from the histories I have recorded and upon which this paper is founded, that variation of temperature in head injuries is invariable, and that in exceptional instances in which it is depressed the severity of associated symptoms will take them out of the category of doubtful cases. In alcoholic coma the temperature is subnormal, and I have found this rule to be absolute. The one case which seemed to be exceptional was reported to me as having a temperature of 100°. Investigation proved it to be the result of petit mal from opium smoking in a young prostitute of the Chinese quarter who had not yet become accustomed to her mode of life. I have made some observations to determine the exact temperature in alcoholic coma. I have succeeded in obtaining upward of INJURIES OF THE HEAD. 89 twenty cases in which coma was more or less profound, and the temperature ranged from 96° to 98°, with a usually full and slow or normal pulse, and the depression of tem- perature was directly proportionate to the depth of coma. I had expected at the present time to have collected a larger number of cases, but I have found my opportunities unex- pectedly limited. Whether it be the quality of whisky or the moral tone of the lower stratum of society which has improved I know not, but examples are no longer to be had for the asking. I believe, however, th§ absolutely uniform results in this number of cases makes it more than probable that a larger number in the future will cor- roborate the conclusion which has been reached. In the diagnosis of apoplexy or non-traumatic cranial ha;morrhage, I have found that the observations of Bourne- ville coincide with those more recently made. They show that in the commencement of the attack the temperature is subnormal, that it then becomes normal, and remains at that point if the patient recovers, but if he dies it rises to a marked degree. In twenty-three cases taken from an accessible record, of which seven proved fatal, the tempera- ture in two of the latter rose to 102° and 104° ; in all the others, fatalities included, the highest temperature was 100° + . This is in marked contrast to traumatic lesions in which the temperature continues to rise from the depres- sion, if one existed, and remains elevated while the result remains in abeyance. A case which suggests the occasional difficulty in the diagnosis of idiopathic from traumatic le- sion is that (Case CVIII) of the man previously quoted who was seized with an apoplectic effusion into his lateral ven- tricles and one occipital lobe, and fell from his cab, causing a cerebellar laceration. There is still another in this series very like it, in which a man after an apoplectic seizure fell backward, and, like the first, lacerated his cerebellum. In 90 A CLINICO-PATHOLOGICAL STUDY OF both cases the previous history was known and it was pos- sible to diagnosticate both lesions. It is unnecessary to refer to uraemic coma, opium nar- cosis, hysteria, etc., as the diagnostic problems they present are elementary. The active delirium which may occur in the period im- mediately succeeding the reception of a brain injury is sometimes very difficult to distinguish from that which re- sults from alcoholic excess. The difficulty may be fur- ther increased by the fact that the subject is of known intemperate habits, and very likely intoxicated when first brought under observation. In those cases in which de- lirium is the first symptom noted, and probably replaces unconsciousness (as in Case I), the condition becomes very deceptive. Tn this instance we are not aided by the tem- perature, which is almost always elevated in alcoholic de- lirium, and elevation may be and often is very great. I have within a few days seen a case in which, with quite ex- tensive superficial injury of the head, there was alcoholism to the verge of delirium, a high temperature, a previous history of epilepsy, and present epileptiform convulsions followed by facial paralysis. The diagnosis, which excluded brain injury and which proved to be correct, was made from observation of the course of the temperature for the first few hours. I am aware of no single diagnostic sign upon which dependence can be placed, and yet I have never seen a case in which it was not possible to make the distinction between the two forms of mental disturbance. There are few head injuries in which there are not at least one or two characteristic symptoms which can be detected if sufficient care be exercised in the examination of the case. It seems to me that there are differences even in the character of the delirium which may be recognized though not easily formulated. INJURIES OF THE HEAD. 91 The diagnosis from each other of the several injuries which may be inflicted upon the cranium and its contents is fraught with difficulties. The lesions are likely to be mul- tiple and the symptoms to be equally referable to either one of their number; the symptoms of circumscribed lesion are often lost in those from one of a diffuse character, and simi- lar results constantly ensue from totally different causes. A more exhaustive study of the diagnostic value of individual symptoms in their relation to each other, and to established structural changes, is therefore requisite than I have yet been able to undertake. There are, however, well-estab- lished facts, as well as strong diagnostic probabilities, which are likely to multiply and to make diagnosis possible in an increasing number of cases. Thus, it is well known that certain haemorrhages positively indicate a definite fracture at the base. A trivial injury of the vertex and one or two general symptoms may suggest its whole extent and com- plications. Again, paralysis of an extremity in a recent head injury will positively determine some lesion of a defi- nite portion of the parietal cortex on the opposite side. In the absence of depressed fracture, and with the knowledge that occurrence of laceration or limited contusion at this point is unusual, the ascription of the paralysis to haunor- rhage becomes justifiable. These conclusions are legitimate and founded upon positive knowledge and logical inference combined. There can be no doubt, I think, that greater diagnostic significance will attach to individual symptoms in the light of further pathological observation. As an ex- ample, the present series of necrologies seem to show that the peculiar mental conditions I have described are usually preceded by lesion of the brain tissue, and if it be of the membranes, that it is meningeal contusion with inflamma- tion. I have insisted upon the importance of temperature in the recognition of head injuries as a class. I am not at 92 A CLINIC0-PATI10L0GICAL STUDY OF present prepared to raise the question of its diagnostic re- lation to individual lesions. PROGNOSIS. The prognosis may be first considered from the numer- ical results. The total number of cases is one hundred and twenty-four, of which forty-nine ended in recovery, or near- ly forty per cent. The fractures at the base number seventy, of which twenty-one ended in recovery, or exactly thirty per cent. The popular belief, and possibly the general professional impression, is that this fracture is a peculiarly fatal acci- dent. I have already expressed the opinion that fracture at the base is devoid of danger except for its complications, but it is so often attended with grave lesions of the brain and meninges that it is not strange that by a species of me- tonymy it should come to stand for the traumatism as a whole. It is difficult to estimate the comparative danger of the several lesions, from the fact that they are so generally mul- tiple, and all together conspire to bring about the fatal re- sult. It is also true that the severity rather than the form of lesion is to be made the basis of prognosis. It may be, therefore, of no great practical importance to attempt to infer from the necropsies the relative responsibility of individual lesions in causing death in each instance. So far as I may judge from comparisons of symptomatology with post-mor- tem appearances, when opportunity has been afforded, I be- lieve death has directly resulted in fully fifty per cent, from laceration and attendant haemorrhage. In the remainder it might be chargeable to epidural haemorrhage, contusion, ab- scess, or arachnitis, though doubtless in every case some other lesion was contributory. The prognosis made from initial symptoms must depend INJURIES OF THE HEAD. 93 upon their general severity and upon the extent to which the vital powers are implicated. It sometimes happens that the patient survives when the obvious extent of the lesion has made recovery seem practically hopeless. A fracture through both middle and one anterior fossa, and probably both, might well put an end to hope, and yet such a case (Case LXIX) did recover. I find that none of my patients have lived in whom the temperature has risen to 105°, but in more than one that degree was approximated. I am not at all certain it might not exceed 105° consistently with re- covery. A very high temperature, or disturbance of respi- ration at an early period, or muscular rigidity, are always calculated to excite the gravest apprehension. The late prognosis presents no difficulties, but it ceases to be of pro- fessional interest. I propose to confine whatever I may have to say in regard to treatment to questions of operation. I omit all reference to medication, as it involves matters of detail for which time is wanting. I premise only a brief men- tion of what may be properly designated adjuvants in gen- eral treatment. The necessity of shaving the head, which is conceded in cases with symptoms of marked severity, is equally existent in every case in which there seems to be a possibility of intracranial injury. It permits the discovery of diagnostic contusions which are so often disclosed only upon post-mortem examination. It relieves the brain, in some cases at least, of a superincumbent and thermogenetic weight, which is positively contraindicated and is a factor of appreciable influence. It facilitates the use of the ice cap, which in cases of high temperature and delirium is an appliance of the highest therapeutic value. I have found it so effective that I desire to emphasize its importance. I have sometimes been compelled to maintain its use for a TREATMENT. 94 A CLINICO-PATHOLOGICAL STUDY OF length of time, as whenever it was discontinued the tem- perature again increased and delirium returned. The resort to a simple form of mechanical restraint is often requisite for the mere purpose of retaining the patient in bed. It incidentally becomes at the same time a means of quieting nervous excitement and of husbanding physical strength. Trephining may be regarded with less apprehension by the timid since the advent of aseptic methods. Its pro- priety may now be decided simply in view of its probable advantage, or its more probable futility7-. It may be counted quite as safe as the use of the exploring needle in suspected abscess, and safer than explorative laparotomy. I should not deem it necessary to insist upon this point were it not that I am so often surprised hv denials of what I had taken to be conceded facts. If, as I am informed, the temperature rises to a high degree after craniectomy or trephining in children, it is so foreign to my experience in traumatism that I am constrained to attribute' it to other causes than to simple perforation of the cranium. 1 have often found it, on the contrary, to be followed by a depres- sion of temperature when no result had been attained be- yond the mere removal of the button of bone. The incis- ion of the dura, or the further exploration of the brain, might be differently regarded, for while trephining, done with due regard to time and method, could hardly inure to the serious disadvantage of the patient, uncalled-for and in- judicious interference with the intracranial contents might be of positive disservice. This possibility is not a contrain- dication to going further after trephining, if its propriety becomes evident. In such case I have always found the temperature to rise as it does in injuries of the brain generally. In the small abscess which I incised through the angular gyrus it rose, in the sixteen hours which pre- ceded death, from 102’2° to 108°. In the very large ab- INJURIES OF THE HEAD. 95 scess in the frontal lobe, upon which I operated only last month, the temperature rose from 99‘2° in twenty-four hours to 102'2°, and recovery is even now complete. I should expect an elevation of temperature in any case, hut I should not expect any serious results from incision of the dura or brain per se. So far as subsequent danger or in- convenience from hernia cerebri is concerned, I may repeat a statement previously made, that in the surgery of to-day it has ceased to be an intimidation to the surgeon. I am quite of the same mind with those surgeons who believe that this operation should be done in every de- pressed fracture where elevation and thorough exploration can not be otherwise accomplished. I believe with them that the absence of general symptoms does not relieve the surgeon from the responsibility of operation. This view was held by my former preceptors, the late Dr. James R. Wood and Dr. J. W. S. Gouley, at a time Avlien to hold such opinion was almost an opprobrium. It commended itself to my judgment then as it does now. It is doubtful if such an operation has been known to do harm when it has failed to do good. It is certain that harm has come in more than one instance where, because of the absence of general symptoms, it has been neglected. It is impossible to tell in a depression of the external table of moderate or perhaps insignificant extent what more extensive comminu- tion of the internal table may not exist. It is this possi- bility of even the smallest bony spicula penetrating the brain and causing serious nervous disturbance in the indefi- nite future that demands thorough examination of every cranial fracture. It should be held obligatory on precisely the same grounds as the examination and cleansing of a wound in the external soft parts. The observance of such precaution is free from danger; its neglect may lead to either present or future serious complications. 96 A CLINICO-PATHOLOGICAL STUDY OF If the depressed fracture is simple or its existence is in doubt, there should be no hesitancy in making sufficiently free incision to determine the exact cranial condition. It is of very common occurrence that a large liaematoma ex- ists in connection with diagnostic symptoms of intracranial injury, and that there is no other means than this of acquir- ing knowledge which may be of vital importance. If the result is nugatory, the incision, made under aseptic condi- tions, will be closed by primary union. It is certainly better to have made many fruitless incisions than to have allowed a single life to be jeopardized by an undiscovered fracture. In case the fracture proves to be a simple ftssure, a different rule of conduct will obtain. The probabilities will be against the existence of depression of the inner table, and after the fissure has been traced, with or without incision, as far as practicable, or till it has become nar- rowed to a line, the wound should be closed. If, how- ever, the general symptoms should indicate complication, further exploration may become proper and necessary. The indications for trephination are wanting at the pres- ent time in the great majority of cases which involve intra- cranial lesion. If the existence of epidural haemorrhage is evident and its location is accessible, the propriety of operation is unquestioned. If the existence of circum- scribed lesion of the brain can be inferred from local paralyses, anaesthesia, or muscular rigidity, or from the initial symptom of convulsion, I think the propriety of operation may be assumed. In the greater number of cases, those in which only symptoms of diffuse lesion can be recognized, the use of the trephine is entirely empirical and without justification, unless undertaken for special reason. If in time lacerations at the base come to be diag- nosticated with reasonable certainty, it may then be proper INJURIES OF THE HEAD. 97 to inquire whether their exposure by the trephine or other- wise, disinfection, and drainage would be practicable and advantagious. The accidental result of trephination, in at least two or three cases, suggests its employment on purely medico-legal grounds. I will instance the case (Case CVIII), already quoted as an example of mixed iodiopathic and traumatic lesions, of a man who fell from his cab after an apoplectic effusion and secondarily lacerated his cerebellum. He was paralyzed, anaesthetic, and absolutely unconscious. He was trephined, and a large amount of serous fluid drained away from the surface of the brain. His temperature fell in six hours from lOS’d0 to 98'6°. He became conscious, could articulate, spoke rationally and intelligently, and gave his name and address. At the end of fourteen hours his tem- perature again rose and he died. The possibilities of such a case are not less practical than dramatic. The instances I have encountered of such transient returns to conscious- ness have been sufficiently prosaic and unimportant. The very next, perhaps, might disclose a criminal and avenge the crime. In any one of the many homicidal assaults in which the victim is found unconscious and the assailant has escaped unknown, I believe it to be legitimate to trephine for this direct purpose. Even temporary restora- tion of the mental faculties might suffice the ends of jus- tice. The prospect of success is certainly not altogether chimerical, for I have cited a case in which just such a hy- pothetical result was absolutely attained. The general principles of operative interference in cra- nial fractures and encephalic injury may be recapitulated and formulated as follows: Incision of the scalp, trephina- tion, incision of the dura mater, and perforation of the brain, severally or together, should have resort without fear or hesitation when indicated. Incision of the scalp and 98 INJURIES OF THE HEAD. trephination are devoid of danger and are always justifiable for exploration, which in itself constitutes an indication. Incision of the dura mater and incision or perforation of the brain are more serious procedures, and should he made only when positively indicated by the general symptoma- tology. I have sketched as rapidly and systematically as possi- ble in this paper the conclusions to be derived from the series of histories and necrologies by which it is preceded. So far as they are confirmatory of previous observations, they will have the value which attaches to independent study. If in any particular they differ from accepted teaching, the inclusion of the historical data will make it easy either to verify their truth or to refute their error. I beg to acknowledge my indebtedness to the courtesy of my colleagues, Dr. J. W. S. Gouley and Dr. F. S. Dennis, and also to the successive house surgeons at Bellevue and St. Vincent’s Hospitals, for their intelligent co-operation in the work of observation.
