Figure 3 Vascular, biliary and visceral changes on multidetector computed tomography. A: Coronal image shows paracholedochal collaterals (arrow heads) indenting the biliary tree (thin arrow) and causing upstream biliary dilatation. Note the normal liver outlines (thick arrow) and enlarged spleen (a); B: Thick maximum intensity projection image depicts portal cavernoma formation (thin arrow), perigastric and pancreatic collaterals (arrow heads); C: Contracted gallbladder with pericholecystic varices (arrow head); D: A patient of extrahepatic portal vein obstruction showing lobulated liver contours (arrow head) and ascites (a).
