Chronic congestive liver / nutmeg liver in computed tomography in an older woman in the portal venous contrast medium phase

The nutmeg liver or autumn foliage liver is the pathological sectional view of a liver of chronic stasis within the organ ( congestion ). Reasons for the decreased venous blood flow from the liver can be an obstacle (e.g. tumor , thrombosis ) between the liver and the right half of the heart. The heart itself can also be the cause of the backwater (for example, an armored heart , pericarditis constrictiva ).

The congestion of blood leads to the formation of congestion roads within the liver lobe . These congestion roads enclose a periportal field (reversal of the lobule structure). Lack of food in the hepatocytes (liver cells) leads to cell death around the central vein of the liver lobule ( atrophy ). There is also an imposing yellowish fat. If such a liver is cut open after death, a picture emerges that is reminiscent of autumn leaves or nutmegs .
