Figure 1. (a) Dynamic contrast enhanced axial CT image of a 55-year-old man with known pancreatic adenocarcinoma. A hypodense, mildly enhancing mass is seen in the pancreatic head and neck involving the common bile duct and proximal portal vein. Note the filling defect in superior mesenteric vein suggests vein thrombosis (large arrow) and retrocaval lymphadenopathy (small arrow). (b) Coronal reformation of the axial source image demonstrates the vascular relation of the mass. Narrowing of the proximal portal vein is exquisitely demonstrated on this three-dimensional rendering (arrows).
