Infrequent Bilateral Orbital Tumors

Abstract

A 44-year-old woman presented with a 1-year history of progressive, painless bilateral proptosis. Magnetic resonance imaging revealed well-circumscribed, enhancing, central masses (Fig A-B). Right mass resection was performed via an inferior fornix incision. Left mass resection was performed via a lateral orbitotomy. Histopathology showed the right-sided mass to be rich in vascular sinuses, lined with flat endothelial cells separated by fibrous intervals (characteristic of cavernous hemangioma, Fig C).
