Hydatid cyst is a parasitic infection due to the larval stage of the tapeworm Echinococcus. It most commonly involves the liver and lung. Location at unusual sites in the body can have atypical presentations and poses a diagnostic challenge. Herein, the authors report a new case of hydatid disease involving the peritoneum and the tunica vaginalis of a cryptorchid testicle in a 57-year-old patient. They conclude that hydatid disease should be kept in mind when a cystic lesion in encountered in the testicle or the peritoneum in endemic areas.
