Liver CT Appearances
Budd-Chiari Syndrome CT Findings
- Patchy enhancement especially in arterial phase with increased enhancement of central portion of the liver
 - Enlarged caudate lobe
 - Compressed IVC
 - Absence of hepatic veins
 - Ascites
 - Regenerating nodules
 - Acute phase
- Early enhancement of caudate love and central portion of liver around IVC, with decreased enhancement of the rest of the liver
 - Delayed enhancement of peripheral portions of liver and central portion of low density (called “flip-flop appearance”)
 - Narrow hypodense hepatic vein and IVC with dense walls
 
 - Chronic
- Failure to visualize IVC or hepatic veins
 - Intrahepatic collateral veins
 - Heterogenous liver enhancement
 - Large avidly enhancing regenerative nodules
 - Marked caudate hypertrophy with peripheral atrophy
