Purpose To report a rare case of orbital alveolar echinococcosis in Iran. Methods A 23-year-old woman with multi-lobular mass lesion in the right orbit underwent excisional biopsy via a deep lateral orbitotomy approach. The pathologic investigation of the lesion was a multilobulated cystic lesion shown where the cyst wall structure was compatible with alveolar Hydatid cyst in histopathology. Clinical course, surgical, and medical management of the disease is noted briefly in the case of orbital involvement of the alveolar echinococcosis. Results Patient was treated with anti-fungal medication, and the cysts were successfully removed by a surgical excision. Conclusion Although orbital alveolar echinococcosis is extremely rare, it is noteworthy to study its clinical manifestations and radiological examinations to be able to make a true diagnosis.
