Intrahepatic stones might mimic cholangiocarcinoma on ERCP

Abstract

Intrahepatic stones are defined as stones in bile ducts proximal to the junction of the left and right intrahepatic ducts. This condition is rare in western countries where it tends to occur in conjunction with Caroli's syndrome, biliary strictures, or any ductal abnormality that results in biliary stasis and infection. This is a report of a case of intrahepatic stones with no such underlying abnormalities and which caused misleading cholangiographic appearances.
