A Rare Case Series of Intraorbital Unilocular Hydatid Cysts in Pediatric Patients

Abstract

Introduction: The orbital hydatidosis due to Echinococcus granulosus accounts for only less than 1% of all hydatid cysts. Here we report a case series of intraorbital hydatid cysts. Case Presentation: This retrospective investigation included two pediatric patients (4 and 13-year-old boys) who were referred because of a progressive proptosis in northwest Iran. Orbital imaging disclosed cystic intraorbital lesions in the cases. Following clinical and surgical explorations, the histopathological evaluation re-confirmed definitely the infertile unilocular hydatid cysts. Conclusions: Differential diagnoses of orbital hydatid cysts from cystic lesions should be explicitly noticed in endemic areas prior to surgery in order to avoid complications.
