Passive Hepatic Congestion

1. Pathogenesis:

• Can cause enlarged liver without focal disease.
   
• Found in patients with CHF, constrictive pericarditis, or restrictive cardiomyopathy.
   
• Passive hepatic congestion is also known as nutmeg liver due to its radiological appearance.

2. Radiographic findings:

• Low attenuation areas in liver caused by chronic increased hepatic venous pressure.



• Note cardiomegaly with enlargments of the right ventricle and inferior vena cava, as well as the hepatic veins (arrows).
