[Fasciola hepatica in the common bile duct. Presentation of a case]

A case of hepatic fascioliasis in the common bile duct is reported in a 54 years female. Upon surgical exploration of the biliary tract, one adult form of hepatic Fasciola was found, without evidence of cholelithiasis. Retrospectively we reviewed the oral cholecystography and the image originally believed to be gallstone, in fact was a hepatic Fasciola. Reviewing past literature, we have not encountered any previous case in which hepatic Fasciola was diagnosed by oral cholecystography.
