²Hacettepe Üniversitesi Tıp Fakültesi Beyin Cerrahisi Anabilim Dalı, Ankara Meningiomas represent approximately 13-26% of primary intracranial tumours. Many small meningiomas have no symptoms during life and may be found incidentally at autopsy. Such incidental meningiomas are detected more frequently in recent years because of the advent of CT and MRI. Malignant (anaplastic) meningiomas are less common lesions, accounting for 1-2.8% of meningiomas. Recently, clear cell and chordoid meningiomas have been classified as WHO Grade II and rhabdoid and papillary meningiomas classified as WHO Grade III tumors without pathological criteria for malignancy. Here we report a rare case of rhabdoid meningioma in a 31 year-old man. Using the presented case we discuss the prognostic significance of recognition of a rhabdoid meningioma in light of the literature.
