[Association of cerebral aneurysm and dural arteriovenous malformation in the anterior cranial fossa: a case report].

A case of dural arteriovenous malformation (AVM) in the base of the anterior cranial fossa associated with a ruptured anterior communicating aneurysm was reported in a 67-year-old man. The dural AVM was fed by the left anterior ethmoidal artery and drained by the left frontal ascending vein with a varicose dilatation. The aneurysm was clipped and the dural AVM was removed in two stages. Dural AVM in the base of the anterior cranial fossa is rare, and we could find only 17 previous reports. Two of them presented with exophthalmos, whereas the remaining 15 cases presented with an intracranial hemorrhage from rupture of the dural AVM. An association of an aneurysm with the dural AVM in this location has not been reported previously.
