Pylephlebitis on CT scan

An axial CT scan (A) shows thrombosis of the left portal vein (arrow) in a 41-year-old patient presenting with pain and fever five months following pancreaticojejunostomy. There are multiple low density foci in the right lobe of the liver (arrowheads). Image B is a CT scan performed one week later and shows a large left upper quadrant abscess (short arrow) and enlarging multicentric intrahepatic fluid collections along the distribution of the portal vein (arrowheads). Left portal vein thrombosis persists (arrow). A drain was placed into the largest abscess (dashed arrow) in the right lobe of the liver.
