Convexity meningioma surgery indications

With the conservative recommendations for surgery for asymptomatic meningiomas and the advent of radiosurgery during the past 10 years, microsurgically treated convexity meningiomas are now typically large in size 1). Nevertheless, the patient's clinical course following microsurgical removal of these lesions is expected to be uncomplicated. 2) 3).

If the convexity meningioma is symptomatic or growing and the patient is of an age in which surgery is appropriate.

If the meningioma is large and has a rich vascular supply, its amenable for a pre-surgery embolization.

The resection of the meningiomas surrounding the dura is an important goal during the removal of a convexity meningioma.

Simpson Grade I resection should continue to be the goal for convexity meningiomas 4).
