Hemangioblastoma of the Optic Nerve

—Case Report—

Abstract

A 64-year-old man presented with a rare sporadic hemangioblastoma arising in the left optic nerve manifesting as left visual disturbance gradually progressive over 5 years. Magnetic resonance imaging revealed a well-enhanced mass in the left optic nerve. Partial resection of the tumor was performed via the frontoorbital approach. The histological diagnosis was optic nerve hemangioblastoma. Hemangioblastoma must be considered in the differential diagnosis of optic nerve tumors even in the absence of other lesions associated with von Hippel-Lindau disease.
