Abstract


Central nervous system hemangioblastomas are generally restricted to the cerebellum, spinal cord, and brainstem. Supratentorial hemangioblastomas are uncommon, and optic nerve hemangioblastomas are extremely rare, with fewer than 25 reports including this case. In this report, we present the case of a 36-year-old woman with von Hippel-Lindau (VHL) disease who presented with progressive diminution of vison in the left eye due to a retrobulbar optic nerve hemangioblastoma. The patient had a history of cerebellar /spinal hemangioblastomas and pancreatic cysts, and her father and brother were patients with VHL disease. Gadolinium enhanced MRI showed intraorbital retrobulbar enhanced mass on the left optic nerve. The optic nerve hemangioblastoma was treated with fractionated stereotactic radiosurgery using Novalis. Eighteen months after the stereotactic radiosurgery, the tumor volume decreased although the patient lost vision. This report presents an extremely rare case of optic nerve hemangioblastoma, which is the first case treated with stereotactic radiosurgery.
