Abstract
Meningiomas are the most common intracranial primary tumor in adults. Traditionally, treatment for growing or symptomatic lesions has focused on surgical resection. However, recently, stereotactic radiosurgery (SRS) has risen as an important treatment alternative or adjunct, especially for larger lesions or those in riskier locations (i.e., skull base or cavernous sinus). Excellent long-term tumor control rates have also been demonstrated in using SRS for benign or smaller lesions. Certain locations (i.e., parasagittal, parafalcine, or convexity) have been associated with lower treatment response rates. In general, morbidity is approximately 10%, with most complications being transient (i.e., peritumoral edema, cranial neuropathies, or seizures). © 2022 selection and editorial matter, Jason Sheehan and L.
