Invasive meningiomas involving the medial sphenoid wing are difficult tumors to resect
completely. They often have invaded the surrounding arteries at the time of diagnosis
making total resection challenging. Attempts at removing these tumors from adherent
carotid or middle cerebral arteries have resulted in high complication rates. Nine
cases of medial sphenoid wing meningiomas with arterial invasion were operated between
March 1994 and August 1998. Total resection was possible in only four cases. Two arterial-related
complications occurred during resection with one resulting in permanent hemiplegia.
