Spontaneous intracerebral hematoma in carotid-cavernous fistula. Report of three cases.
Spontaneous intracerebral hematoma associated with carotid-cavernous fistula is rare. Three new cases are presented. In each, the hemorrhage originated in the vicinity of localized intracranial venous engorgement, as demonstrated by cerebral angiography. Rupture of one or several of the distended venous channels from increased back-flow is postulated as the etiology of the intraparenchymal hematomas.
