Hepatic atrophy

Last revised by Daniel J Bell on 30 Mar 2023

Hepatic atrophy is a common appearance on imaging of the liver. It may result from obstruction of a major branch of the portal vein, bile ducts or hepatic veins. It does not usually occur secondary to hepatic arterial flow compromise. Compensatory hypertrophy of the unaffected segments/lobes is common, leading to the so-called atrophy-hypertrophy complex.
