Increased hepatic echogenicity with posterior acoustic attenuation: What does it mean and what should be done?

Normally, increased and dense hepatic echogenicity with posterior attenuation shown in ultrasound imaging may be caused by obesity, long-term alcohol consumption, non-alcoholic fatty liver disease, viral hepatitis, cirrhosis, and other conditions. Management typically involves weight reduction, abstinence from alcohol, and medication therapy. If abnormalities are detected, timely medical consultation is recommended. Detailed explanations are as follows:

1. Obesity: Excessive body weight and abnormal fat metabolism can lead to excessive fat accumulation in the liver, causing increased and dense intrahepatic echogenicity and posterior echo attenuation on ultrasound examination. It is recommended to control diet, reduce intake of high-fat and high-calorie foods, increase physical activity, lose weight, and improve hepatic fat accumulation.

2. Long-term alcohol consumption: Alcohol is primarily metabolized in the liver, and prolonged alcohol consumption can damage liver cells, affecting the liver's normal structure and function, thereby presenting as increased and dense intrahepatic echogenicity and posterior echo attenuation on ultrasound. Complete abstinence from alcohol is necessary to prevent further liver damage. Additionally, maintaining a light diet and supplementing with vitamins and proteins are recommended.

3. Non-alcoholic fatty liver disease: Excessive fat deposition in the liver leads to hepatic cell fatty degeneration, resulting in abnormal liver ultrasound images, including increased and dense intrahepatic echogenicity and posterior echo attenuation. This condition is often accompanied by symptoms such as fatigue and discomfort in the right upper quadrant of the abdomen. Treatment mainly involves following medical advice to use medications such as polyene phosphatidylcholine capsules, silymarin capsules, and reduced glutathione tablets, combined with dietary and exercise interventions.

4. Viral hepatitis: Hepatitis virus infects the liver, causing inflammation and necrosis of hepatocytes and fibrotic changes in liver tissue. Ultrasound examination reveals increased and dense intrahepatic echogenicity and posterior echo attenuation, often accompanied by symptoms such as loss of appetite, jaundice, fatigue, and liver area pain. Doctors generally recommend treatment with entecavir dispersible tablets, tenofovir disoproxil fumarate tablets, compound glycyrrhizin tablets, etc.

5. Cirrhosis: Long-term progression of various chronic liver diseases leads to diffuse liver fibrosis and formation of pseudolobules, with destruction of liver architecture. Ultrasound examination shows increased and dense intrahepatic echogenicity and posterior echo attenuation, often accompanied by symptoms such as ascites, gastrointestinal bleeding, weight loss, and fatigue. It is recommended to use medications such as spironolactone tablets, furosemide tablets, and Fuzheng Huayu capsules under a physician's guidance; liver transplantation may be required in severe cases.

In daily life, maintaining a healthy lifestyle, controlling body weight, avoiding long-term alcohol consumption, and undergoing regular liver ultrasound and liver function tests are important to detect and address liver abnormalities promptly and protect liver health.
