Hypoechoic area of about 3.3*2.4cm in size and irregular morphology is seen in the liver, which needs to be clarified to determine the etiology before deciding whether treatment is needed. Hypoechoic dark area in the liver may be intrahepatic cysts, hemangiomas, fatty liver, cirrhosis, hepatocellular carcinoma and so on. 1. Liver cysts are usually larger than five centimeters and need to be treated if they are accompanied by symptoms. Moreover, most of the liver cysts are sterile, so they do not need to be treated for the time being, and regular checkups and observation are sufficient; 2. Liver hemangioma is a benign disease, which can be left untreated for the time being, and usually avoid strenuous exercise. 3. For people with fatty liver, if there are no obvious symptoms and other tests are normal, they can be left untreated for the time being, and usually pay attention to a light diet. 4. If it is cirrhosis or liver cancer, it needs to be treated as early as possible. Cirrhosis should be treated according to the cause of cirrhosis, while liver cancer requires comprehensive treatment mainly based on surgery. It is necessary to go to the hospital in time to get a clear diagnosis and treatment plan, and use medicines under the guidance of the doctor, avoiding self-medication.
