Complete Spontaneous Regression Of A Cerebral Arteriovenous Malformation
Southern Medical Journal 80(4): Apr 1987; 529-532
View Original Source →Abstract
A case of intraventricular hematoma in the lateral ventricle, caused by rupture of a small arteriovenous malformation is reported. The location and size of the hematoma were documented by pneumoencephalography 7 weeks after the hemorrhage occurred. Spontaneous recovery of function to the prehemorrhage level occurred and a second air study 3 months after the onset of symptoms revealed virtually complete disappearance of the hematoma. The literature relevant to the problems of intraventricular hematoma is reviewed.
Case Details

Remission Characteristics
Complete cessation of seizures and headaches as well as resolution of papilledema, with visual fields returning to normal
Treatment & Mechanisms
Proposed Remission Mechanisms
Not discussed
Clinical Treatment
Anticonvulsants and dexamethasone
Additional Notes
The AVM was supplied primarily by a hypertrophied left anterior choroidal artery together with some posterior choroidal vessels, and there was early filling of the basal vein of Rosenthal. The branches of the middle cerebral artery had returned to their normal position and the anterior choroidal artery was of normal caliber. The supply from the posterior circuit had also disappeared.
