Abstract
Complete resection of meningiomas occurring at the skull base may be difficult, due to the proximity of critical neurovascular structures. Due to the benign nature of these lesions, most patients with skull base meningiomas have an extended life expectancy. The goal of treatment for these lesions, therefore, revolves around long-term tumor control without worsening neurological function. Stereotactic radiosurgery is one of three main treatment options for the treatment of cranial base meningiomas, and has been shown to have similar rates of tumor control with safe administration within 3–5 mm of cranial nerves and brainstem. In this chapter, we review the literature reporting outcomes following use of stereotactic radiosurgery for these lesions, and the rationale for decision-making about treatment for these lesions.
