ABSTRACT
In a series of 375 bilateral carotid angiographies, two accessory middle cerebral arteries, one duplication of the middle cerebral artery demonstrated on the angiography were reviewed relative to the pertinent literature. These anomalous middle cerebral arteries are very rare. We reported a case of duplication of the middle cerebral artery at 1993 which was first one to be reported in Korea. At present, we report two additional anomalous accessory middle cerebral arteries. Among these, one was accessory middle cerebral artery originated from the horizontal portion of the anterior cerebral artery, and the other originated from the A2 segment of the anterior cerebral artery. Both of these gave rise to some perforating arteries.

'Duplication of the middle cerebral artery' is a rere vascular anomaly of the brain. The authors experienced a case of duplication of the middle cerebral artery in a patient with a posterior communicating artery aneurysm. It was demonstrated by angiography and confirmed at surgery. The neck of aneurysm was successfully clipped. Postoperative course was uneventful.
