Convexity Meningiomas

Abstract

Convexity meningiomas, as their name implies, are tumors that arise from the convexity of the skull vault and have dural attachments that do not involve any of the dural venous sinuses and are not related to the falx or substantially to the skull base. Convexity meningiomas have the greatest potential for cure as they ideally lend themselves to total removal, including the involved dura. Approximately 90% of all meningiomas are supratentorial, with around 15–19% being located in the region of the convexity (1,2). These meningiomas occur almost two to three times more frequently in females (3), with the uncommon malignant meningioma being more frequent in males (4).
