Thirty two cases of supratentorial meningiomas diagnosed by computerized tomography and surgically proved are reported. The authors did not included in this series meningiomas of the orbit. The higher frequency is observed in the convexity area (eleven cases), followed by the sphenoidal ridge area (nine cases). There is a predominance in the females (65,6%) over the males (34,3%). The age varies from fourteen to seventy eight and only three patients are below thirties. Homogeneous contrast enhancement of all tumours was obtained by injecting a bolus of 75ml of Vasconray (30g of total iodine per patient) or 80ml of Hypaque 75 (30,8g of iodine), None of them showed the ring pattern observed in cases of abscess, gliomas or metastatic lesions. The edema seen around the tumours tended to be minimal, unless in those tumours located in the frontal region where the mass effect tended to be more pronounced. Hidrocephaly was observed in three cases.
