====== Convexity meningioma treatment ======

Because of their location on the brain’s surface (as opposed to deep within the brain), [[convexity meningioma]]s are typically easier to treat than other types of [[meningioma]]s. 

If the meningioma is small and produces no symptoms, a “watchful waiting” approach, which involves regular MRI scans to monitor its growth is recommended.

Stereotactic radiosurgery: For those patients in whom surgery is not advisable or the meningioma is unresectable, radiation therapy can be used to treat small incompletely removed tumors and certain tumor recurrences.

===== Preoperative embolization of intracranial meningioma =====
[[Preoperative embolization of intracranial meningioma]]

[[Tumor embolization]] may be best reserved for large hypervascular [[convexity
meningioma]]s. Usually performed 24 hours to 1 week preoperatively. The [[devascularization]] causes
attenuation in intraoperative blood loss and the resultant [[necrosis]] frequently renders the tumor
softer and easier to remove. However, tumor [[swelling]] may occur and occasionally an emergency
[[craniotomy]] may be required
