Calcified and ossified meningiomas / Calcified and ossified meningiomas

RESUMO

Seven cases of meningiomas with areas of calcification and ossification are reported, comprising 2.5 per cent of our 274 cases meningiomas. Six of these tumors ocurred in women (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 not found in the literature. In case 2, there was late recurrence of a tumor of entirely different histopathological features. Multiple, small osterogenic meningiomas, possibly associated with Von Recklinghausen's disease, were found in the right temporal lobe in case 5.
