Hepatomegaly is enlargement of the liver. [4] It is a non-specific medical sign , having many causes, which can broadly be broken down into infection , hepatic tumours , and metabolic disorder . Often, hepatomegaly presents as an abdominal mass .
Steatosis, also called fatty change, is abnormal retention of fat within a cell or organ. [1] Steatosis most often affects the liver – the primary organ of lipid metabolism – where the condition is commonly referred to as fatty liver disease. Steatosis can also occur in other organs, including the kidneys, heart, and muscle. [2]
Fatty liver disease can occur in pets such as reptiles (particularly turtles [48]) and birds [49] as well as mammals like cats and dogs. [50] The most common cause is overnutrition. A distinct sign in birds is a misshapen beak. Fatty livers can be induced via gavage in geese or ducks to produce foie gras. Fatty liver can also be induced in ...
Metabolic dysfunction–associated steatotic liver disease (MASLD), previously known as non-alcoholic fatty liver disease (NAFLD), [a] is a type of chronic liver disease. This condition is diagnosed when there is excessive fat build-up in the liver ( hepatic steatosis ), and at least one metabolic risk factor.
In the initiation phase, a pro-oxidant hydroxyl radical (OH•) abstracts the hydrogen at the allylic position (–CH 2 –CH=CH 2) or methine bridge (=CH−) [clarification needed] on the stable lipid substrate, typically a polyunsaturated fatty acid (PUFA), to form the lipid radical (L•) and water (H 2 O).
Edema may also involve the hands, trunk, and face. Kwashiorkor is characterized by a fatty liver. This fatty liver of the undernutrition phenotype is often accompanied by evidence of inflammation and fibrosis. Whereas a fatty liver of undernutrition is a consistent feature of kwashiorkor, it is only encountered sometimes in children with marasmus.
Stearoyl-CoA desaturase (SCD; EC 1.14.19.1) is an iron-containing enzyme that catalyzes a rate-limiting step in the synthesis of unsaturated fatty acids. The principal product of SCD is oleic acid , which is formed by desaturation of stearic acid.
Focal fatty liver (FFL) is localised or patchy process of lipid accumulation in the liver. [1] It is likely to have different pathogenesis than non-alcoholic steatohepatitis which is a diffuse process. FFL may result from altered venous flow to liver, tissue hypoxia and malabsorption of lipoproteins.
