title: Orbital hydatid cyst: an unusual presentation.
abstract: PURPOSE. To describe an unusually large and long-standing hydatid cyst of the orbit causing gross disfigurement of the eyeball. METHODS. Detailed investigations, consisting of radiological and hematological studies, were carried out to determine the cause of the unusually severe and long-standing proptosis. The patient underwent orbital exploration for the presumed diagnosis of orbital echinococcosis.The entire cyst with the globe was removed and sent for histopathological examination. RESULTS. The gross and histopathological findings of the specimen removed surgically confirmed the diagnosis of orbital hydatid cyst. CONCLUSION. The diagnosis of orbital hydatid cyst should be considered in unilateral severe proptosis of long duration with gross disfigurement of the globe and orbital walls.
