Extrahepatic biliary cancer: New staging classification

Figure 10 Distal bile duct tumors. Post-contrast computed tomography (CT) examination of the abdomen in a 65-year-old female with cholangiocarcinoma of the bile duct. CT image of the distal bile at the level of the pancreas shows a soft tissue tumor (yellow arrow) in keeping with the tumor. The tumor extends to the superior mesenteric artery (red arrow). There is a biliary stent in place (blue arrow). Radiologically, appearances are consistent with a T4 tumor due to involvement of superior mesenteric artery.
