Intraosseous meningioma of the skull is a rare benign tumor. A case of calvarial origin examined with computed tomography and bone scintigram is reported. The tumor was located in the left fronto-temporo-parietal region, involving the superior orbital fissure. Total removal of the tumor was performed and histological diagnosis of intraosseous meningioma was obtained. Radiological findings and possible histogenetic mechanism of the intraosseous meningioma are discussed.
