Tentorial arteriovenous malformation presenting as an intracerebral hematoma

Abstract

A case of tentorial arteriovenous aneurysm is reported in a 54-year-old man. This malformation, fed by branches of the external carotid artery, was drained exclusively by a parieto-occipital cortical vein. The rupture of this vein was responsible for the presenting intracerebral hematoma.
