Background: This study aimed to report on the case of a child with the manifestation of orbital cellulitis which was finally diagnosed as an orbital hydatid cyst.
Case report: The case is a 5-year-old girl with an isolated orbital hydatid cyst presented with slowly progressive proptosis, deterioration of vision, chemosis, periorbital swelling, and palpebral edema. Evaluations for other organ involvements including liver and lung were negative. A cystic orbital mass lesion with enhancing walls was found in orbital Computed Tomography (CT) scanning. The cyst was removed completely through the upper lid crease incision and treatment continued with systemic albendazole. The patient was followed for three months with a favorable outcome.
Conclusion: We should consider the diagnosis of a hydatid cyst in a child with the signs and symptoms of orbital cellulitis, specifically in endemic areas.
