Figure 5 Extrinsic invasion of the common hepatic duct by gallbladder carcinoma in an 80 years old woman with jaundice. A: MinIP (coronal oblique 14.3 mm thickness slab) image shows dilatation of the intrahepatic bile duct caused by an irregular mass (arrows) in the common hepatic duct, which is the result of direct invasion from the irregular wall thickening (arrowheads) of the gallbladder (GB). This image depicts well the relationship between gallbladder carcinoma and the obstructed biliary duct; B: PTC demonstrates only the biliary obstruction without any suggestion of the cause.
