Aneurysmal subarachnoid haemorrhage which has a serious mortality and morbitity ratio, occurs approximately 10/100 000 population per year and it is usally caused by rupture of a cerebral artery aneurysm. Aneurysms are classified sacculer, fusiform or dissecan by morphlogical description. Vascular congenital anomalies of the cerebral vessels contribute to saccular aneurysm formation by increasing hemodynamic stress on the vessel wall. Although anterior communicating artery (ACoA) is the most seen site of vascular anomalies associated with aneurysmal formation, the agenesis of the anterior commmunicating artery is very rare. Here, we present unusual anatomical variations of ACoA detected by three-dimensional CT angiography after subarachnoid hemorrhage.
