Primary hydatid cyst of the gallbladder is an unusual and very rare localization of hydatid disease. So far only five cases that fulfill the criteria of primary gallbladder hydatidosis have been published in the English medical literature. Case presentation We report a case of a 39-year-old Kosovan Albanian woman referred to the Abdominal Surgery Division of the University Clinical Center of Kosovo for a calcified hydatid cyst of the liver with gallbladder involvement . Her history was significant for chronic right upper quadrant pain characterized as intermittently colicky pain accompanied by nausea. The patient underwent right subcostal laparotomy. Intra-operatively a calcified primary hydatid cyst of the gallbladder was found. Its pericyst was tightly attached to the liver. Complete pericystectomy with cholecystectomy followed. The histopathology confirmed the presence of calcified hydatid cyst of the gallbladder and that the cyst had developed entirely extra-mucosally. Five year follow-up showed no recurrence of disease. Conclusion Primary hydatid cyst of the gallbladder is a very rare clinical entity. Accurate preoperative diagnostic localization is not always easy particularly in centers with limited diagnostic tools.

Three broad morphological forms of echinococcosis are recognized clinically. Human cystic .
