Thickening of liver echo is one of the results of ultrasound examination, and the normal result is usually a uniform echo in the liver. Thickening of liver echoes usually indicates substantial liver lesions and liver cell damage, which may be accompanied by symptoms such as pain in the liver area and fatigue. Thickened liver echoes may be related to fatty liver, viral hepatitis, liver cancer, liver fibrosis, cirrhosis and other diseases. 1. Fatty liver: If patients drink a lot of alcohol for a long time and consume too much fat, it can lead to damage of liver cells and fatty liver caused by fat deposition, which can result in thickening of liver echoes. 2. Viral hepatitis: Various types of viral hepatitis can lead to degeneration of liver parenchyma and damage to healthy liver cells, which can lead to thickening of liver echoes in ultrasound examination. Most of the patients with viral hepatitis also have jaundice, fever, loss of appetite and other symptoms. 3. Hepatocellular carcinoma: If the patient suffers from hepatocellular carcinoma, it will lead to the appearance of abnormal tumor cells in the liver parenchyma, which will generally lead to thickening of liver echoes. The patient may be accompanied by abnormal weight loss, hidden pain in the right upper abdomen and so on. In addition, thickening of liver echoes may also be caused by liver fibrosis or cirrhosis, and tests such as liver stiffness measurement should be performed to clarify the specific cause. Liver lesions are often insidious, and there are usually no obvious clinical symptoms in the early stage. Even if patients do not have symptoms such as pain in the liver area, nausea, vomiting, etc., they should go to the hospital as soon as possible for relevant examinations to clarify whether there are organic lesions of the liver.
