A 48-year-old female developed multiple cerebral aneurysms in association with atypical moyamoya disease. At the age of 43, the basilar-superior cerebellar artery junction aneurysm was clipped successfully. Four years later a new aneurysm developed at the interpeduncular segment of the left posterior cerebral artery. It enlarged, ruptured, and was clipped successfully. Operative indication for cerebral aneurysms in the presence of cerebrovascular moyamoya disease based on radiological and operative findings, as well as their mechanism of development, are discussed.
