Hydatid cysts usually present as hepatic or pulmonary lesions, but in our case, it presented in the gallbladder with three symptomatic daughter cysts in the CBD. Echinococcus caused by E.granulosus Is the most common parasite causing the disease, accounting for 95% of the cases. Case presentation: 75 - year - old male presented with colic pain, jaundice, itching, vomiting, nausea, insomnia, Positive murphy's sign, and elevated AST and ALT. Total bilirubin was also elevated with no hepatomegaly or splenomegaly.

Which can come from the portal system or the spreading of brood capsules through the biliary tract. Conclusion: The method of investigation used was USG, CT, ERCP which are affordable and accessible in low-income countries including Syria. we would like to highlight this rare presentation and the possibility of using laparoscopic surgery.
