Calcified and ossified meningiomas

RESUMO

Seven cases of mengiomas with areas of calcification and ossification are reported, comprising 2.5 per cent of our 274 cases meningiomas. Six of these tumors occured in womwn (85,7 per cent). Six were located intracranially, and one within the spinal canal. The osteogenic meningioma in case 1 was situated within Meckel's cave, rare location of ossified meningioma that we have no found in the literature. In case 2, there was late recurrence of a tumor of entirely different histopathological features. Multiple, small osteogenic meningiomas, possibily associated with Von Recklingghausen's disease, were found in the right temporal lobe in case 5
