Intracranial lipoma associated with cerebral saccular aneurysm. Case report.

The authors present a case of lipoma in the sylvian fissure associated with a saccular aneurysm of the middle cerebral artery. The aneurysm was successfully clipped following the partial resection of the tumor. This is the first reported case of this combined pathology. The value of cerebral angiography in this disease entity and the possible etiology of the association of an aneurysm with a lipoma are discussed.
