Abstract: Objective To assess the therapeutic effect of gamma knife radiosurgery for residual tumors after surgical resection of hemangioblastoma in children. Methods The clinical data were retrospectively analyzed in 9 children who received gamma knife radiosurgery for the residual tumors after a previous surgery for hemangioblastoma resection. Results The 9 children were followed up for 12-48 months, and 6 children showed a tumor volume reduction by over 50% with obviously improved clinical symptoms. One child showed no response to the treatment and received a second gamma knife radiosurgery. In 2 children, the tumor volume increased progressively after the radiosurgery, and a second radiosurgery was performed in 1 case and open surgery in the other. Conclusion Gamma knife radiosurgery is safe and effective for treatment of the residual tumors in children with previous surgical resection of hemangioblastoma.
