Interrogation revealed a long-term history of living with Echinococcus granulosus endemic area, associated to close contact with sheep and dogs. Upon physical examination, a painless mass of the left hypochondrium, fixed to the deep plane. Abdominal ultrasonography (USG) showed a 9 cm encapsulated mass in contact with the tail of the pancreas. Further investigation was carried out by performing an abdominal computed tomography (CT) scan showing: large cystic mass with a partially calcified thickened wall, containing multiple vesicles, measuring 11.5 cm, located at the tail of the pancreas. The patient was put under Albendazole for a week and then operated on. During laparotomy, a hydatid cyst was located in the tail of the pancreas. Conservative treatment was done sparing the healthy pancreatic parenchyma and avoiding major surgery for a diabetic patient.
