Unusual localization of hydatidosis: Hydatid cyst of gallbladder

The case of a 38-year-old man suffering from hydatid cyst located in the gallbladder is presented. Although Morocco remains an endemic area for echinococcosis, this presentation of the disease is rare. Pericyst was tightly attached to the liver. Complete pericystectomy followed by cholecystectomy was done. Histopathology confirmed the presence of calcified hydatid cyst of the gallbladder. Perioperative adjuvant medical therapy with albendazole was administered. In a 2-year follow-up, no recurrence has occurred.
