Budd-Chiari syndrome

Mottled peripheral hypodensity to the right liver, mainly in the periphery of segments V, VI, VII and VIII. The right and middle hepatic veins do not opacify. The left and caudate lobes of the liver have a normal appearance with normal opacification of enlarged left hepatic veins. The portal veins opacify normally. As best as can be determined the peripheral right portal vein branches opacify normally. The hepatic artery is not well seen secondary to timing of the CT. Splenomegaly.

Cholecystectomy. Adrenal glands, kidney and pancreas have a normal appearance. No free fluid or free gas.

Bilateral pleural effusions, larger on the left. Minor bibasal atelectasis.

Conclusion:

Appearances are of right liver hypoperfusion, probably from venous congestion from complete right and middle hepatic vein thrombosis. This represents Budd-Chiari syndrome.
