Draining into the collateral vessels is the dilated splenic vein. The superior mesenteric vein and its tributaries are likewise dilated and appear to drain into the afore mentioned collaterals. The right and left intrahepatic branches of the portal vein are attenuated.
The liver shows mild atrophic left lateral segments (segment II and III) with hypertrophy of the caudate lobe and segment IV, the liver shows fat density.
Wandering spleen is mildly enlarged and seen at the left lumbar region.
