Cavernous hemangioma of the optic disk.

PURPOSE: To report a case of an unusually large cavernous hemangioma of the optic disk. METHOD: Case report with funduscopic, fluorescein angiography, and magnetic resonance imaging correlations. A 20-year-old woman with no ocular or systemic history was diagnosed with cavernous hemangioma of the optic disk in a routine eye examination. RESULTS: Fundus examination revealed an extremely large cavernous hemangioma of the optic disk, almost 4.5 disk diameter. Fluorescein angiography showed delayed filling of the lesion with intravascular plasma-erythrocyte separation and no leakage. No systemic involvement was found. CONCLUSION: This case represents an atypical presentation of cavernous hemangioma of the optic disk, among the largest reported in the literature. After a 5-year follow up period, no change has been documented.
