Metastatic colon carcinoma simulating primary bile duct carcinoma via endoscopic cholangiography.
A case of metastatic colon carcinoma simulating primary bile duct carcinoma is presented. The radiographic similarities via endoscopic retrograde cholangiopancreatography include bile duct narrowing and mucosal destruction. A distinguishing feature, however, is failure of the intrahepatic bile ducts to dilate in metastatic carcinoma to the biliary tree.
