Oncocytic meningiomas have been recently reported as a rare variant of meningiomas. Immunohistochemical analysis shows that neoplastic cells are positive for antimitochondrial antibodies. We report our first patient with oncocytic meningioma, presenting with intratumoral bleeding. A 72-year-old woman suffered from a disturbance of consciousness. A CT scan showed a tumor with intratumoral hemorrhage. An emergency craniotomy was performed and the tumor and hematoma were removed. Examination of the tumor revealed meningothelial cells with oncocytic change. We discuss the clinicopathological considerations of this uncommon variant and review the pertinent literature.
