title: Traumatic intraconal hematic cyst of the orbit.
abstract: A 35-year-old man with a history of repeated previous facial injuries presented with acute onset of a right orbital mass less than 2 weeks after blunt trauma to the right eye. Orbital B-scan ultrasonography and computed tomography showed an intraconal cystic lesion. The tumor was excised via lateral orbitotomy. Pathologic evaluation demonstrated a hematic cyst containing fresh blood. The presence of hemosiderin in the cyst wall suggested recent bleeding in a preexisting orbital hemorrhagic lesion. Patients with hematic cysts of the orbit usually present with a subperiosteal mass months to years after trauma.
