Disappearance and Development of Cerebral Aneurysms Associated with Cerebrovascular Moyamoya Disease

Abstract

A case of multiple cerebral aneurysms associated with cerebrovascular moyamoya disease was reported.
In this case, reduction and disappearance of bilateral internal carotid artery aneurysms and the enlargement and accompanying new development of basilar artery aneurysms were demonstrated on follow-up cerebral angiograms. Possible mechanisms of the disappearance and development of cerebral aneurysms in the presence of cerebrovascular moyamoya disease were discussed.
