Cavernous transformation of the portal vein

Case contributed by Dr Bita Abbasi

Patient Data

Gender: Male
Modality: CT

Appearances in this contrast enhanced CT scan obtained during portal venous phase:

Enhancing lesions with beaded appearance are seen at the porta hepatis. These represent the collaterals which have replaced the thrombosed portal vein. The collaterals also extend to the intraparenchymal portal branches, pericholecystic collaterals and coronary veins.
Other visible signs of portal vein thrombosis are hypertophy of liver segment IV and Caudate lobe and atrophy of left and right lobes. Note right displacement of the gallbladder fossa due to segment IV hypertrophy.

Case Discussion

In the contrast enhanced CT scan obtained during portal venous phase:

Multiple tortous vessels are seen at the porta hepatis. These represent the collaterals which have replaced the thrombosed portal vein. The collaterals also extend to the intraparenchymal portal branches, pericholecystic collaterals and coronary veins. Other visible signs of portal vein thrombosis are hypertophy of liver segment IV and Caudate lobe and atrophy of left and right lobes. Note right displacement of the gallbladder fossa due to segment IV hypertrophy. Ascitis is most likely due to portal hypertension.
