Atrophy of segments 2, 3, and 4 of the liver with hypertrophy of the caudate lobe of the liver with a heterogeneous enhancement of liver parenchyma on portal venous phase due to chronic main portal vein thrombosis.
Multiple dilated tortuous venous channels are seen replacing the fibrotic and chronically thrombosed main portal vein - suggestive of cavernous transformation of the portal vein.
These dilated tortuous venous channels are seen surrounding the gallbladder, cystic duct, common hepatic and common bile duct, causing narrowing of the distal common bile duct and resultant dilatation of common bile duct and dilatation of intrahepatic biliary radicals (segments 6, 7, and 8).
There is also dilatation of duodenum and proximal jejunal loops secondary to a long segment jejunal stricture showing wall thickening and peripheral fat stranding.
Post splenectomy changes are seen.
