It is essential to identify the anatomic variations of neurovascular structures in terms of preventing complications which may develop during neurosurgery and interventional neuroradiological procedures. It is necessary to be aware of the middle cerebral artery (MCA) outlet anomaly to understand collateral blood flow in events of cerebral ischemia related to duplicated or accessory MCA in cerebral aneurysm surgery. Intracranial vascular anomalies involving the MCA are relatively rare. Duplicated MCA has been reported at rates of 0.2%-2.9% in literature. In this paper, the imaging findings of a 71-year old male with duplicated middle cerebral artery are presented in whom the complaints of mildly ataxic step and cloudy consciousness were present.
