Multiple Aneurysms in the Anterior Communicating Artery: Case Report

ABSTRACT

Multiple aneurysms arising from the same intracranial artery are rare. A few cases of multiple aneurysms of the anterior communicating artery(ACoA) have been reported in the literature. The authors present a 60-year-old female patient who had multiple aneurysms on the ACoA with systemic vasculitis. There were four aneurysms around the ACoA region. Two sizeable aneurysms had completely separated necks on each side of the ACoA. The ruptured larger aneurysm projected in an anteroinferior direction, whereas the unruptured smaller one projected superoposteriorly. Both aneurysms were surgically confirmed and clipped. Two bleb-like microaneurysms, located on ACoA and perforating artery each, were coagulated and reinforced.
