Primary osteolytic intraosseous meningioma of the frontal bone

Abstract
Almost 1–2% of meningiomas are lesions described as ectopic or extradural meningiomas. Primary intraosseous meningiomas are a rare form of intra-bone tumours that account for approximately 67% of extradural meningiomas.
A 41-year-old male patient presented with a headache and a bulge at the right frontal region. Cranial computed tomography displayed a hyperostotic lesion. Magnetic resonance imaging showed enhancement of the bone lesion after injection of gadolinium. A burr hole was drilled at the thickest section of the lesion, and pathological examination of the bone dust extracted from this site was performed. The pathological study indicated the presence of a meningioma. Right frontal craniectomy was performed and the hyperostotic bone was resected. No invasion was observed at the dura. A calvarial defect was reconstructed during the same session with methyl methacrylate cranioplasty.
