Intracerebral arteriovenous malformation supplied by ethmoidal arteries--case report.
An intracerebral arteriovenous malformation supplied by bilateral ethmoidal arteries in a 51-year-old male is described. Operation revealed a vascular conglomerate on the cerebral surface which formed an arteriovenous shunt. The feeding artery and draining vein were clipped and incised, and the malformation was removed en bloc. An intra- or extracerebral vascular anomaly supplied by the ethmoidal artery is thought to be derived from a similar developmental fault, in which an arteriovenous shunt becomes trapped in an extradural location, the dura mater, the subdural space, or the cerebral parenchyma, during later fetal development.
