Meningioma constitutes 14% to 20% of intracranial neoplasms and only 1 % are extradural. Extradural tissue includes the skin, the neck, the paranasal sinuses, the nasal cavities and the diploe of the cranial bones. The intra osseous tissue refers to the diploe of the cranial bones. Primary intraosseous meningiomas are seldom correctly diagnosed preoperatively and are usually mistaken for primary bone tumors and hyperosteotic en plaque meningiomas. Primary intra osseous meningioma is a rare entity, but the diagnostic criteria are not yet well defined. A case of primary intraosseous meningioma is reported here and the related literature is reviewed. Anahtar Kelimeler : Hyperostosis, intra osseous meningioma, calvarium
