Cystic meningioma = six cases

We report six cases of meningioma, uncommon tumors which accounted for 2.7 of al meningiomas observed in our series. Computed tomography was performed in all patients and product the diagnosis in only 40 % of the cases. Surgi cal treatment was given. Histological examinations of the surgical specimen s confirmed the diagnosis. CT and magnetic resonance imaging were sometimes misleading, suggestive of metastasis or glioblastoma. Selective carotid ar teriography with opacification of the external carotid artery established t he diagnosis. Prognosis was good after surgery.
