Stereotactic radiosurgery for benign neoplasms

Over the last decade, the use of stereotactic radiosurgery (SRS) for the treatment of intracranial lesions has grown significantly. In addition to malignant brain tumors and vascular malformations, benign tumors have also been treated with SRS. Although surgical resection has long been considered the gold standard in the management of such benign lesions, the outcomes of SRS in various benign neoplasms appears to be comparable. In this review, we will examine the literature as it pertains to the treatment of benign brain tumors with SRS. Of particular note, we will examine the results of SRS in acoustic neuromas, meningiomas, pituitary adenomas, and other benign tumors.
