Abstract

Primary orbital involvement is extremely rare in echinococcosis. We report a case of giant orbital hydatid cyst in a 15-year-old boy. A 15-year-old boy presented with left-side proptosis and gradual painless vision loss. Computed tomography and magnetic resonance imaging revealed a giant multilocular cystic orbital lesion extending into subfrontal region. Surgical excision was done. Histopathology was suggestive of hydatid cyst. Postoperatively, an antiparasitic agent was administered for 3 months. Hydatic cyst should be kept in differential diagnosis of orbital cystic lesions, especially in pediatric population and endemic areas.
