Stereotactic radiosurgery of intracranial meningiomas

Abstract

Stereotactic radiosurgery (SRS) has been performed for intracranial meningiomas for more than 30 years. Small to moderate-sized meningiomas are generally considered good candidates for SRS because of their neuro-imaging and radiobiological characteristics. Patient selection is critical for successful meningioma SRS. Factors related to tumor control and radiation-related complications in patients with WHO grade I or presumed meningiomas include history of prior surgery, tumor volume, and tumor location. Patients with small volume, nonoperated skull-base or tentorial meningiomas typically have the best outcomes after SRS.
