Arteriovenous Malformation Leading to Triple Aneurysm of the Posterior Inferior Cerebellar Artery: A Rarity
Abstract: Aneurysmal rupture is the most common cause of spontaneous non traumatic subarachnoid and intraventricular haemorrhage. Saccular aneurysms (aka Berry aneurysm) are the most common phenotype of intracranial aneurysm that arise from branch points of major cerebral arteries with maximal hemodynamic stress. 10% of these aneurysms are seen to involve the posterior circulation. Posterior inferior cerebellar artery (PICA) is a branch of vertebral artery and is an uncommon site for intracranial aneurysm. The present report describes a 50-year old chronic alcoholic and hypertensive with history of sudden onset altered sensorium presenting with multiple aneurysms in the PICA associated with arteriovenous malformation on CT angiography scan.
Keywords: triple aneurysm, posterior inferior cerebellar artery, arteriovenous malformation, subarachnoid haemorrhage
