Accessory middle cerebral artery

Case report

Restricted access

✓ An anomalous vessel is reported in a patient with an anterior circulation aneurysm. The presence of an accessory middle cerebral artery arising from the postcommunicating segment of the anterior cerebral artery is described. The clinical relevance and possible etiology of the anomaly are reviewed.

    Left internal carotid angiograms, anteroposterior (left) and oblique (right) views. An aneurysm is seen pointing medially and interiorly, with its origin at the junction of the left A1 segment and the anterior communicating artery. There is also an accessory middle cerebral artery (m.c.a.) arising from the left A2 segment. i.c.a. = internal carotid artery.

    Diagram showing the operative findings. The accessory middle cerebral artery (MCA) arises from the left A2 segment of the anterior cerebral artery (AC2). The aneurysm originates at the junction of the left A1 segment of the anterior cerebral artery (AC1) and the anterior communicating artery. ICA = internal carotid artery.
