Overview

The predominant therapy for meningioma is surgical resection. Adjunctive radiation therapy may be required among certain patients.

Surgery

The predominant therapy for meningioma is surgical resection. Adjunctive radiation therapy may be required among certain patients.

Transarterial embolization has become a standard preoperative procedure in the preoperative management

If invasion of the adjacent bone occurs, total removal is nearly impossible.

The probability of a tumor recurring or growing after surgery may be estimated by comparing the tumor's WHO (World Health Organization) grade and by the extent of surgery by the Simpson Criteri

Simpson Grade	Completeness of Resection	10-year Recurrence
Grade 1	Complete removal including resection of underlying bone and associated dura	9%
Grade 2	Complete removal and coagulation of dural attachment	19%
Grade 3	Complete removal without resection of dura or coagulation	29%
Grade 4	Subtotal resection	40%
