Angiographic disappearance and reappearance of an arteriovenous malformation of the cerebellum and brain stem, and its surgical excision a case report

Abstract

A case of arteriovenous malformation (AVM) of the cerebellum and brainstem at the cerebellopontine angle is reported. Though a postoperative angiogram after the first operation indicated complete excision of the lesion, the patient returned with subarachnoid haemorrhage, and an angiogram indicated reappearance of the lesion. Total excision was carried out at the second operation.
