A 67-year-old woman presented with bilateral distal anterior cerebral artery aneurysms manifesting as consciousness disturbance. Computed tomography revealed subarachnoid hemorrhage in the interhemispheric fissure, right sylvian fissure, and a hematoma in the right frontal lobe and lateral ventricles. Angiography showed bilateral symmetrical aneurysms located on the pericallosal artery at the bifurcation of the callosomarginal artery. The operation was performed on the day the patient was admitted. The aneurysms were clipped via the interhemispheric approach, and the hematoma was aspirated. Operative view demonstrated rupture of the left aneurysm, and supreme anterior cerebral aneurysm. Postoperative angiography showed disappearance of the aneurysms and an intact bilateral anterior cerebral artery. The patient was discharged with mild organic mental syndrome. However, a few days later, she was admitted again with a high fever and died of complications due to sepsis. Pathological view showed clipped aneurysms and the connection of the bilateral distal anterior cerebral artery with the so-called supreme anterior communicating artery.
