In patients with cirrhosis, the presence of thickened parenchymal echogenicity of the pericardium is an imaging sign that suggests possible liver pathology, such as cirrhosis, and widening of the portal vein is usually thought to be the result of portal hypertension due to cirrhosis. Imaging of the liver with thickened parenchymal echogenicity is suggestive of liver disease, such as fatty liver, autoimmune liver disease, and cirrhosis. Accompanying portal vein widening generally refers to widening of portal vein, which is a pathway for gastrointestinal blood to flow into the liver, and its widening suggests that the diameter of the main trunk of the portal vein exceeds the normal range, suggesting that there is an increase in upstream or downstream flow, which is usually considered to be the result of portal hypertension caused by liver diseases such as cirrhosis and hepatocellular carcinoma, leading to portal vein widening. Therefore, the imaging phenomenon of patients with cirrhosis presenting with thickened parenchymal echogenicity of the liver envelope without smoothness accompanied by portal vein widening is consistent with the manifestation of cirrhosis. If the diagnosis of cirrhosis is confirmed and the test result shows that the liver pericardium is not smooth and the parenchymal echogenicity is thickened with portal vein widening, it is recommended to go to the hospital and ask the doctor to make a comprehensive judgment in combination with one’s own situation.
