Multiple peripheral aneurysms of the posterior inferior cerebellar artery: Case report and review of the literature

Abstract

Multiple peripheral aneurysms of the posterior inferior cerebellar artery (PICA) are extremely rare. We describe a patient with four distinct aneurysms in the peripheral segments of the left PICA successfully treated surgically with an excellent outcome. Pathological examination of the excised aneurysmal sac showed no evidence of infectious etiology.
