Stereotactic radiosurgery has had an increasing role in the treatment of selected intracranial lesions in pediatric patients. In our first 44 months experience, 60 of the patients (9%) treated were less than or equal to 18 years of age. Current indications for radiosurgery include primary treatment of high-risk arteriovenous malformations or acoustic neurinomas (usually in patients with neurofibromatosis), adjuvant treatment for recurrent benign tumors after surgery, or as adjuvant treatment to fractionated irradiation for malignant tumors.
