Abstract

Craniotomy and resection is usually a safe and effective treatment for hemangioblastoma. However, since the surgical removal of recurrent and multifocal tumors can be associated with greater risks, stereotaxic radiosurgery was used to ablate hemangioblastomas in four patients with von Hippel-Lindau disease. In two of these cases a symptomatic lesion was surgically resected just prior to radiosurgery. The 11 radiosurgically treated tumors (four patients) were spherical and varied in diameter from 0.75 to 2.0 cm with a mean of 1.25 cm. Dose ranged from 30 to 75 Gy with a mean of 35 Gy. After a mean clinical and radiologic follow-up of greater than 1 1/2 years, tumor size and/or cyst formation was controlled in all cases. Nevertheless, it was necessary to temporarily shunt a tumor cyst in one patient. In another case, aggressive treatment resulted in symptomatic radiation necrosis. Despite such potential problems we believe that radiosurgical tumor ablation is a reasonable alternative to craniotomy and/or radiation therapy in poor risk patients. This report is believed to be the first published description of the use of radiosurgery in the treatment of hemangioblastoma.
