Leptomeningeal angiomatosis and aplasia congenita of the scalp. Case report.

This 9-year-old boy had two circular areas of aplasia congenita of the scalp in the territory of the first division of the trigeminal nerve and an ipsilateral parieto-occipital leptomeningeal capillary venous angioma. He had an associated giant aneurysm of the distal posterior cerebral artery on the same side as the vascular malformation. The patient had a long history of seizures and presented with intracerebral bleeding. This case may be considered as a variant of Sturge-Weber syndrome. Further observations must be added to consider this entity as a separate neurocutaneous disease.

Extrathecal cavernous hemangioma.

A case of extrathecal cavernous hemangioma, a rare entity, is presented. Some clinical, radiological, and histological features of the lesion are discussed. The unusual dumbbell-like growth of the tumor through an intervertebral foramen is considered, as well as the potential effectiveness of radiation therapy. The literature dealing with spinal hemangiomas and hemangioblastomas is summarized.

Traumatic interhemispheric subdural hematomas.

Two cases of traumatic interhemispheric subdural hematoma are reported. The first patient had combined convexity and parasagittal subdural hematomas; the second patient had an interhemispheric subdural hematoma which extended over the tentorium. Although most reported cases have followed a subacute clinical course with characteristic lower-extremity monoparesis, both our patients deteriorated rapidly 24 and 48 hours after the injury without warning neurologic signs and died in spite of prompt surgical treatment. Both cases were diagnosed with computerized axial tomography (CT). This examination is particularly valuable in defining the extent of the hematoma and its possible association with other lesions.

Giant cerebral capillary telangiectasis in an infant.

The authors describe an unusual and unique case of a giant capillary telangiectasis of the right frontal lobe encountered in a 10-month-old child. The patient presented with progressive neurologic symptoms mimicking a brain tumor. The lesions was resected in toto with good clinical results.

Spinal extrathecal hemangiolipomas: report of two cases and review of the literature.

Two cases of a rare entity, spinal extrathecal hemangiolipoma, are presented. The clinical and histological features of the tumor are discussed, with particular attention to the uncommonly sudden onset of symptoms in one patient. Complete neurological recovery was exhibited by one patient after excision of the lesion, whereas only a partial recovery was achieved in the other case. The pathogenetic aspects of hemangiolipomas and the literature dealing with the previously reported 12 cases are reviewed.

Traumatic intracerebellar hematomas.

Seven patients with "isolated" traumatic intracerebellar hematomas due to closed head injuries are presented. Computerized tomography parameters useful in the correct management of these hematomas include: location (hemisphere or midline), size, and appearance of the posterior fossa cisterns (intact or obliterated). Three patients with hemispheric hematomas were treated conservatively and recovered. One patient with a midline hematoma was managed conservatively and died. Three hematomas (one hemispheric and two midline) were operated on. The immediate results of surgery were good, but two patients died later due to medical complications. The results of this study support the concept that large hematomas (3 cm or greater) generally need surgery and that hemispheric hematomas of limited size (less than 3 cm) may be treated conservatively. The clinical course of prognosis of midline hematomas is grave, and evacuation of accessible hematomas should be considered early in the course of the disease.

Resolution of occlusion in spontaneously dissected carotid arteries. Report of two cases.

Two cases of internal carotid artery occlusion secondary to spontaneous dissection are reported. Both patients presented with transient ischemic attacks. both had antiplatelet aggregation therapy, followed by spontaneous resolution of the occlusion. The period of healing seems to be relatively short. In both cases, restoration of flow was angiographically documented 14 days and 10 weeks after the initial arteriogram. Strategies for treatment of such patients are discussed.

Traumatic aneurysms of the supraclinoid internal carotid artery.

This paper describes two patients with traumatic aneurysms of the supraclinoid internal carotid artery, which occurred after a closed-head injury and without demonstrable basal skull fracture. In the first case, the traumatic origin of the aneurysm was demonstrated by repeat angiograms. The second case documents the formation of a giant, traumatic, true aneurysm of the supraclinoid carotid artery over a period of less than 2 months; there was an associated traumatic partial occlusion of the vessel proximal to the aneurysm. The mechanisms of injury of the supraclinoid carotid artery are discussed.

Giant aneurysm of the pericallosal artery. Case report.

A case is reported of a thrombosed giant aneurysm of the pericallosal artery. Neurological presentation was attributable to the acute swelling of the aneurysmal mass after rapid and massive intraluminal thrombosis. This case demonstrates that initial symptoms in giant aneurysms may be related to the thrombotic events within the enlarged sac. The computerized tomography characteristics of this case are reported and discussed.

Benign traumatic intracerebellar hematoma.

Prompt surgical intervention is thought to be necessary in patients with traumatic intracerebellar hematoma. The case reported here ran a benign course without operation. Pertinent serial computed tomographic scans are presented. It is concluded that not all traumatic hematomas of the cerebellum require operations.

Microsurgical removal of paraventricular cavernous angiomas. Report of two cases.

Two cases of paraventricular cavernous angiomas are presented. In one, the cavernous angioma was found in the right wall of the fourth ventricle, and in the other in the right thalamus encroaching upon the third ventricle. Both patients had onset of symptoms suggesting a tumor. Good results were obtained by the microsurgical approach to these malformations. The computerized tomography findings typical of cavernous angiomas are reviewed

Subacute and chronic extradural hematomas: a study of 30 cases.

The authors report 30 cases of extradural hematomas with prolonged course: the interval between injury and development of clinical signs was more than 48 hours. Twenty-nine were operated upon. These delayed cases have a mild clinical course and a better prognosis than the acute. Contrary to the reports that many subacute and chronic epidural hematomas are located other than temporally, the present series shows the high incidence (83%) of temporal lesions. Of the patients 74% recovered and returned to their previous occupations: the two deaths were from causes not directly related to the injury and hematoma. We conclude that most subacute hematomas arise from various, often combined, low-tension sources of bleeding. The importance of recognizing gradual neurologic deterioration and performing craniotomy in these patients is emphasized.

Cerebral cavernous angiomas in children.

Five cases of cerebral cavernous angiomas in children are presented. Three children had seizures as the sole manifestation of the lesion, and two had intracerebral bleeding. These malformations are encountered more commonly in adults in the third to fifth decade, and are found most frequently in the white matter of the cerebral hemispheres. Intracranial bleeding, seizures, headaches, and slowly developing focal signs are the usual presenting complaints. In childhood, seizures are the initial symptom of the malformation in many cases. The value of computerized tomography (CT) in the detection of such malformations is stressed, and CT findings that are characteristic of cavernous angiomas are described.

Fracture of the distal radius with ulnar nerve palsy.

A patient with immediate palsy of the ulnar nerve secondary to a distal fracture of the radius and possibly a dislocation of the distal radio-ulnar joint (Galeazzi's fracture) is described. Surgery demonstrated a serious contusion of the nerve, scarring around the nerve, and thrombosis of the ulnar artery. Symptoms rapidly disappeared after neurolysis.
