Dural Arteriovenous Malformation in the Anterior Fossa

A case of dural arteriovenous malformation in the anterior fossa is reported. It first caused a subarachnoid hemorrhage and subsequently an intracerebral hematoma. Pertinent literature is briefly reviewed. Such malformations may be divided into three groups; those involving primarily the basal dura mater of the anterior fossa, the anterior portion of the falx, or the dura mater of the frontal convexity. Principal blood supply comes from the ophthalmic artery with an additional supply from the external carotid system. The treatment of choice is surgical excision with or without artificial embolization of the feeding arteries from the external carotid artery.
