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
