Abstract
Introduction: hydatid disease, is endemic in méditerranéen countries. Primary hydatid cyst of the gallbladder is an unusual and very rare localization of hydatid disease. around thirty cases fulfill the criteria of primary gallbladder hydatidosis have been published.
Case Presentation: We report a case of a 43-year-old woman referred to surgical outpatient department for “homogeneously hypoechogenic hydatid cystic oval mass with partially calcified wall in segment 4 of the liver measuring 9.5 × 11 cm”. Her history showed mild tenderness of the right upper quadrant of the abdomen accompanied by vomiting. Hydatid serology tests (ELISA) were positive. The patient underwent right laparotomy. Intra-operatively, primary hydatid cyst of the gallbladder with partial calcified wall was found. Complete pericystectomy with cholecystectomy followed. The histopathology confirmed the presence of calcified hydatid cyst of the gallbladder. three year follow-up showed no recurrence of disease.
Conclusion: Primary hydatid cyst of the gallbladder is a very rare and unusual clinical entity. Accurate preoperative diagnostic localization is not always easy. Treatment of choice is open cholecystectomy with pericystectomy. Compare to liver hydatidosis, the gallbladder primary hydatid cyst has a better prognosis.
