1.1.  Background: Hydatid cyst is a rare parasitic infection that can involve almost all organs caused by tapeworms of the genus Echinococcus. It is endemic in sheep-raising and cattle-raising areas worldwide. The most common site of involvement is liver followed by lungs. The orbital involvement as a rare location, associates with 0.3 % – 2 % of prevalence.

1.2.  Case presentation: Herein, we report the case of a 6-year-old boy with slowly progressive proptosis of his right eyeball of 8 months duration, with recent progressive diminution of vision for 2 months. The presumptive diagnosis of hydatid cyst was based on the clinical finding, the life-style of the patient, and the diagnostic imaging techniques that showed a cystic lesion in the intraconal space of the right orbit. Surgical removal was carried out; the cyst was enucleated via fronto orbital approach. Histopathological examination confirmed the diagnosis of hydatid cyst. The patient remained disease free with regular follow-up for 2 years.

Conclusions: Orbital hydatid cyst should be included in the differential diagnosis of unilateral proptosis. The treatment is surgical excision followed by the systemic use of Albendazole
