Hydatid disease is a zoonotic disease caused most frequently by Echinococcus granulosus and Echinococcus multilocularis. A periappendiceal primary location is extremely rare. The case of a 63-year-old patient is presented. She is from a high Andean region in Cusco. She has had contact with cattle, sheep, and dogs. She had symptoms of disease for a period of approximately 10 years. The predominant symptoms were abdominal pain in the right hemi-abdomen. The physical examination revealed a mobile tumor mass in the right iliac area. The ultrasound scan evidenced cholelithiasis and complex cystic mass in the lower right hemi-abdomen, suggesting peritoneal hydatidosis. A total cholecystectomy and cystectomy was performed (with adherence to cecal appendix). Histopathological results confirmed the diagnosis of a periappendiceal hydatid cyst measuring 3.94 x 3.15 inches, and acute catarrhal appendicitis. The importance of this case is based on the unusual location of a primary hydatid cyst.
