Epidermoid Tumor of the Bony Orbit: Case Report

Epidermoid cyst originating within the diploic space of the bony orbit is rare. The authors describe two cases of epidermoid cyst of the orbit. The clinical presentation was dependent on the location of the slowly expanding epidermoid cyst. Proptosis caused by intraorbital extension of the mass was the presenting sign in both case. The finding in orbit CT scan appeared to be specific for intradipolic epidermoid cyst. Their clinical presentations and surgical management were briefly discussed.
