Overview
CT scan may be helpful in the diagnosis of Budd-Chiari syndrome. Contrast-enhanced computed tomography (CT) is performed in portal venous phase ,this helps to obtain good contrast filling in the portal, mesenteric, and hepatic veins and in inferior vena cava for detection of associated pathology. 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.
CT
- CT scan may be helpful in the diagnosis of Budd-Chiari syndrome.[1][2][3]
- Contrast-enhanced computed tomography (CT) is performed in portal venous phase ,this helps to obtain good contrast filling in the portal, mesenteric, and hepatic veins and in inferior vena cava for detection of associated pathology.
- 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
