Abstract
Abstract Anterior communicating artery (ACoM) and anterior cerebral artery (ACA) are the most common locations of anomalous variations and aneurysm formation. Infraoptic origin of ACA is an extremely rare anatomical variant. This case report illustrates an extremely rare anatomical variation of bilateral infraoptic origin of ACA with ruptured ACoM aneurysmal subarachnoid hemorrhage. The authors detail this case in the light of the available literature and operative nuance in its management. For the treatment of a complex situation, accurate understanding of the anatomic variations, intraoperative three-dimensional orientation, proper imaging study, and extremely careful technique are essential.
