[A case of duplication of the middle cerebral artery associated with arteriovenous malformation of the temporal lobe].
A rare case of duplication of the middle cerebral artery associated with an arteriovenous malformation of the left temporal lobe is reported. A 45-year-old man was admitted to our clinic on January 7, 1985 with a history of sudden onset of headache and nausea, followed by loss of consciousness for 20 minutes. Neurological signs were negative on admission. An arteriovenous malformation of the left temporal lobe fed by a duplicated middle cerebral artery and the original MCA were demonstrated on left carotid angiography. No other vascular lesion was observed on the angiograms. The arteriovenous malformation was successfully removed on January 17, 1985. Postoperative course was uneventful. Embryological relation of duplication of the middle cerebral artery to other cerebrovascular anomalies is briefly discussed.
