Liver lesions are various types of lesions that occur in the liver. Liver lesions mainly include viral hepatitis, steatohepatitis, cirrhosis, and hepatocellular carcinoma. Viral hepatitis is a common infectious disease characterized by degeneration and necrosis of the parenchymal cells of the liver caused by the hepatitis virus. Steatohepatitis is a condition in which the liver cells contain a large number of lipid droplets and push the nuclei to one side, resulting in enlarged and rounded liver cells. Cirrhosis is a degeneration characterized by chronic progressive, diffuse degenerative necrosis of hepatocytes, fibrous tissue proliferation within the liver, and nodular regeneration of hepatocytes as the basic pathology. The liver is the center of the body’s material and energy metabolism, involved in the body’s metabolism, detoxification, excretion, coagulation, and immunity and other processes, so the liver lesions should pay attention to, and should be actively treated.
