Gamma knife radiosurgery for circumscribed choroidal hemangioma

The authors report a case of circumscribed choroidal hemangioma (CCH) treated by stereotactic radiosurgery with gamma knife. A thirteen-year-old boy presented with a 4-year history of progressive visual loss in his right eye. Because of the large size and fluid collection under the macula, gamma knife radiosurgery was done. During 2 years of follow-up, there was resolution of retinal detachment, regression in tumor thickness, and no complications. Gamma knife radiosurgery may be a reasonable alternative treatment option for symptomatic CCHs which are difficult to manage using standard therapeutic options such as photocoagulation.
