Cholangitis Due To Cholecysto-Hydatid Cyst Fistula.

A 36-year-old female patient was referred to our department with the complaint of acute abdominal pain in the right hypochondrium, fever, and jaundice. Laboratory findings were suggestive of obstructive jaundice and an increase in infectious parameters. Ultrasound and abdominal CT scan showed a 43*41*56 mm cystic formation of segment IVb of the liver communicating with the gallbladder via a fistula, as well as a discrete dilatation of the main bile duct (Figure 1).
