The description of hepatic parenchyma with coarse and heterogeneous echogenicity refers to the liver's echo pattern. Normally, the hepatic parenchyma exhibits relatively uniform echogenicity, and the intrahepatic ductal system appears clearly defined.However, when there is an increase in the coarseness of hepatic parenchyma echogenicity, several conditions may be present:1. Liver parenchymal damage caused by hepatitis viruses, specifically hepatitis. In China, hepatitis B is the most common. In such cases, long-term viral load can lead to liver cell damage, resulting in enhanced hepatic parenchyma echogenicity.2. Patients with chronic anemia, which may cause increased coarseness of hepatic parenchyma echogenicity. It is necessary to conduct a complete blood count and splenic ultrasound to check for splenomegaly.3. Patients who have undergone radiation therapy or chemotherapy, where the coarseness of hepatic parenchyma echogenicity is due to drug and radiation-induced damage to liver tissue.
