Malignant meningioma is rare and its initial clinical course tends to be short but otherwise indistinguishable from that of benign meningiomas. And although it has been noted that many of them have propensities for invading the dural venous sinuses, the skull, and even extracranial tissues by direct spread, there seems little tendency for these to metastases. The chances of recurrence and eventual death are high in malignant meningioma.
Recently we have experienced a case of malignant meningioma involving the right frontal bone and frontal lobe with infiltration to the adjacent structures.
