Abstract

|
Primary extradural meningioma is about 1?2% of all meningiomas. Primary intraosseous meningioma is a rare form of intra-bone tumors that account for approximately 67% of extradural meningiomas. We report a primary intraosseous meningioma of a 69-year-old man who had headaches and a mass on right parietal scalp for the past few months. Remarkably, the brain tissue within the osteolytic cavity of the skull was normal in computed tomography and magnetic resonance images. Resection, duraplasty, and cranioplasty were performed. The patient’s symptoms disappeared after surgery, and the histological diagnosis was an osseous meningothelial meningioma (World Health Organization grade I).
