Moyamoya disease associated with aneurysm –Cerebral ischemia in patient with subarachnoid hemorrhage

Abstract

Moyamoya disease is cerebrovascular disease with stenosis of intracranial arteries and formation of multiple random collateral blood vessels at basal cistern. It can present as hemorrhagic or ischemic complications. Aneurysm in moyamoya disease is very rare, which can rupture leading to subarachnoid hemorrhage and secondary vasospasm leading to ischemia of cerebral lobes. We present a case of young woman with Moyamoya disease presenting with Subarachnoid hemorrhage secondary to rupture of basilar artery aneurysm, later developing cerebral cortical infarct.
