Convexity Meningioma: Principles of Resection

Convexity meningiomas develop from the leptomeninges of the cerebral convexities over all lobes of the brain and represent 15-20% of intracranial meningiomas. Due to their accessible location, distance from the skull base and the dural venous sinuses, they offer the greatest potential to achieve their radical gross total resection. Their excision should encompass a wide dural margin and the involved bone, especially for young patients, to decrease the risk of tumor recurrence.

Similarly, convexity meningiomas were among the earliest accessible s...
