Orbital hydatid cyst is rare and represents a small percentage of all echinococcal systemic locations. It is usually a primary echinococcosis. A new case of orbital hydatid cyst with asymptomatic coexistent lung and liver cysts is described in a child.
Methods and results
The patient underwent surgical excision of the lung and liver cysts and successful application of albendazole treatment for orbital echinococcal cyst without evidence of recurrence after a 4-year follow-up.
Conclusions
Hydatid cyst should be included in the differential diagnosis of unilateral exophthalmos in patients from countries where echinococcosis is endemic.
