title: Interposition of the gallbladder--or the absent common hepatic duct and cystic duct.
abstract: Interposition of the gallbladder is a rare anomaly, but its diagnosis is important since it represents a surgically correctable cause of jaundice. The patients present with jaundice, abdominal pain and sometimes an enlarged gallbladder. Radiological diagnosis may be difficult since the condition may be mistaken for a choledochal cyst, hydrops of the gallbladder or Caroli's disease. The ultrasound, cholangiogram and surgical findings of dilated intrahepatic ducts adjacent to a normal or enlarged gallbladder with no dilatation of the common bile duct are presented in two children with this condition.
