Orbital hydatidosis is incommon, accounting for 1 to 2 % of all localizations. It caused by Echinococcus granulosis. The modern imaging (CT-MRI) contribute in the preoperative diagnosis, however the diagnosis of certainty is confirmed by postoperative anatomopathology. Herein, we report the case of a right intraorbital hydatid cyst in a 12year-old child. He has benefited from an ocular ultrasound year, orbital-cerebral CT and an orbital MRI, which conclude by a bilobal cystic formation seat of calcifications, centered on the lateral rectus muscle of the right orbit pushing the neighboring organs blowing the roof of the orbit, without sign of intra cranial extension. A second hydatid localization is revaluated by thorax radiography and abdominal ultrasound. The patient received a CT scan after the surgery that showed partial regression of the hydatid cyst.
