A solid hypoechoic 9.1cm x 5.2cm x 8cm in the left lobe of the liver may be a benign mass such as intrahepatic hemangioma or a malignant tumor such as hepatocellular carcinoma. 1. Benign mass: it may be hepatic hemangioma, intrahepatic inhomogeneous lipoma and nodular hyperplasia and other diseases. If there is no previous combination of viral hepatitis, alcoholic cirrhosis, viral cirrhosis and other diseases, then the possibility of benign is higher. 2. Malignant mass: it may also be malignant diseases such as hepatocellular carcinoma, including primary hepatocellular carcinoma, hepatoblastoma, metastatic hepatocellular carcinoma and so on. Especially patients with history of liver cirrhosis or obvious systemic symptoms, such as obvious weight loss, fever, abdominal pain, etc., the possibility of liver cancer increases, and it is recommended to combine with other examinations, such as abdominal CT, alpha-fetoprotein, etc., for identification. If the diagnosis is not clear, liver puncture biopsy or liver angiography can be done to clarify the diagnosis. The solid hypoechoic 9.1cm×5.2cm×8cm in the left lobe of the liver needs to be taken seriously, and further examination should be carried out in cooperation with the doctor, so that the diagnosis can be clarified and the patient can be treated aggressively if necessary.
