There is a female predominance link previous radiation therapy. On imaging, they appear as homogenously enhancing lesions distinct brain, cause significant mass effect edema associated “tail.” Surgical treatment can cure patient provided complete resection including attachments bone invasion removed well. If surgical not accomplished, radiosurgery used treat residual disease. Grade III meningiomas have higher risk for recurrence should always treated postoperative therapy when there disease even resection. Specific strategies different locations in brain given this chapter.
