CT

• CT scan may be helpful in the diagnosis of Budd-Chiari syndrome.
• Findings on CT scan suggestive of Budd-Chiari syndrome include:
  • Early enhancement of the caudate lobe and central liver around the inferior vena cava
  • Delayed enhancement of the peripheral liver with accompanying central low density (flip-flop appearance)

inhomogeneous mottled liver (nutmeg liver)

• • Peripheral zones of the liver may appear hypoattenuating because of reversed portal venous blood flow

inability to identify hepatic veins

• • In the chronic phase, there is caudate lobe enlargement and atrophy of the peripheral liver in affected areas
