Figure 3. (a) MRCP clearly demonstrates pancreatic juice leak through the pancreatic pseudocyst-portal vein fistula (arrowheads), liver dome (arrow) and into the peritoneal cavity (asterisks). (b) Intraoperative pseudocystography via a catheter (arrow) shows the pseudocyst-portal vein fistula (arrowheads). Note a large amount of contrast material spilling into the duodenum (asterisk); this accounted for the inability to demonstrate pancreatic leak. b, common bile duct; ps, pancreatic pseudocyst.
