Anatomic variations of the circle of Willis may cause cerebral aneurysm formation. Azygos Anterior Cerebral Artery (aACA) is the existence of A2 segments of the anterior cerebral artery as a single vessel. In the presence of aACA, aneurysm development is more common than normal anatomic structure. Azygos Anterior Cerebral Artery (aACA) aneurysms often develop at the level of the corpus callosum genu and bifurcation. We present a patient who was admitted to the emergency department for intracerebral hematoma, and was operated due to saccular aneurysm developed at the bifurcation of callosomarginal artery, the first branch of aACA.
