The intracranial meningiomas are tumors in general of benign type of a slow growth originating in the arachnoid cells layer, especially in arachnoid granulations. The anaplastic or malignant meningiomas accounted for only the 1-3%. Sometimes they simulate malignant neuroepithelial lesions due to its fast growth and the frequent invasion of surrounding cerebral tissue with very frequent relapses and many times they required adjuvant therapy. The topographic images of this type of tumor are hyper-denses with a good contrast capture, regular and well defined with not much or not associated edema, quite the contrary that observed in present case where images seems to correspond with those of a malignant glioma (multiforme glioblastoma).

Keywords : Meningioma; anaplastic meningioma; malignant meningioma.
