A Rare Case of Dissecting Aneurysm of Extradural PICA Presenting with Subdural Hemorrhage

Abstract

Neha Choudhary*, Chirag K Ahuja and Chirag Jain

Subdural hematoma (SDH) occurs from interruption of bridging or superficial cerebral veins, most commonly from head trauma. Rupture of an intracranial aneurysm may rarely lead to SDH with or without subarachnoid or intraventricular bleed. We report a rare case of ruptured dissecting aneurysm of an extradural posterior inferior cerebellar artery (PICA) leading to spontaneous subdural hematoma and explain possible mechanisms.
