BACKGROUND: @entity808 are uncommon @entity5 of the brain often treated by surgical resection. Surgery may be associated with high morbidity. OBJECTIVE: We present a series of @entity808 treated with linear accelerator radiosurgery during a 19-year period. METHODS: This is a retrospective analysis of @entity1 who underwent treatment of @entity808 at the University of Florida with linear accelerator radiosurgery between August 1989 and February 2008. Forty-nine @entity1 underwent treatment during the study period, and 6 were lost to follow up. The mean age was 51 years (range, 17-82 years), 39% had previous surgical resection, and 67% presented with preradiosurgery @entity129 . There were 25 trigeminal, 18 jugular foramen, 2 facial, 2 oculomotor, 1 hypoglossal, and 1 high cervical @entity808 . The median @entity5 volume was 5.3 mL (range, 0.3-24.5 mL), treated with a median dose of 1250 cGy (range, 1000-1500 cGy). Study endpoints were actuarial local @entity5 control and neurological outcome. RESULTS: Forty-three @entity1 were available for a median follow-up of 37 months (range, 6-210 months). Actuarial local @entity5 control was 97% at 1 year, 91% at 4.5 years, and 83% at 5 years. There were 4 new @entity129 (9%) including facial @entity1183 (2 @entity1 ), anesthesia dolorosa (1 @entity1 ), and @entity425 (1 @entity1 ). Thirty-nine percent had documented clinical and/or symptomatic improvement. There were no other morbidity and no mortality with treatment. CONCLUSION: Radiosurgery for @entity808 offers good actuarial local @entity5 control and has superior morbidity compared with surgical resection. This is the largest linear accelerator radiosurgical series, and the second largest radiosurgical series reported to date.
