What does liver parenchyma mean?

What does liver parenchyma mean?

The liver parenchyma is mostly comprised by liver cells (hepatocytes). The major supporting cells are Kupffer cells and stellate cells. Kupffer cells are the resident mononuclear phagocytes. In quiescent state, the stellate cells are responsible for vitamin A storage and metabolism.

Is parenchyma present in liver?

Liver. The liver parenchyma is the functional tissue of the organ made up of around 80% of the liver volume as hepatocytes. The other main type of liver cells are non-parenchymal. Non-parenchymal cells constitute 40% of the total number of liver cells but only 6.5% of its volume.

What is normal liver parenchyma?

The liver parenchyma is composed of small lobules of a roughly hexagonal shape with portal tracts at the apices. Inside the lobules, the hepatocytes are arranged as cords of cells connecting the portal tracts in the periphery to the central veins (terminal branch of hepatic veins).

What does it mean to have parenchymal liver disease?

Parenchymal liver disease affects the actual liver cells directly instead of those of supporting tissue, such as the bile ducts. According to Dictionary.com, the word “parenchymal” is an anatomical term that refers to the “specific tissue of an animal organ.”

What does increasing echogenicity of the liver parenchyma?

Fatty change: Increased echogenicity means that on a sonogram study the liver had a lighter or whiter appearance than is typical. This is called fatty infiltration and can be caused by many things such as medications like cholesterol lowering drugs and many other medications.

What do you mean by the term homogeneous parenchyma?

The term homogeneous parenchyma means that the all aspects of the liver tissue are similar, it is enlarged but there is no particular area that appears markedly different from the other. Homogeneous means same.

What is parenchymal liver disease?

Liver disease: Hepatomegaly means that the liver is larger than is normal. Parenchyma is the main tissue of the liver. Diffuse parenchymal disease means that there is diffuse disease throughout the liver tissues. This could be due to many different causes so check with your doctor for further information.

What is increased liver parenchymal echogenicity?

Increased echogenicity of the liver usually means that there is fatty infiltration in parts of the liver. In certain causes a focal area of increased echogenicity would indicate a discrete mass. However, in your case, a diffuse increase would mean a fatty liver.
