Liver hypoechoic mass shadow, which is a descriptive term for liver ultrasound, may be liver cysts, liver abscesses and liver cancer. 1. Liver cysts: For patients with small diameter liver cysts, observation and treatment is sufficient, and regular review of abdominal ultrasound is required, usually once every 3-6 months, to understand the changes of liver cysts. 2. Liver abscess: in case of liver abscess, anti-infection and pus drainage treatment are needed. 3. Hepatocellular carcinoma: It is necessary to further improve relevant examinations, such as abdominal MRI or abdominal enhanced CT examination, alpha-fetoprotein and relevant tumor markers, and perform surgical resection of the tumor after clarification, and send pathological biopsy to clarify the nature of the tumor after operation. Hepatic hypoechoic mass may also be other causes. Patients with intrahepatic hypoechoic masses need further examination to clarify the diagnosis, and then actively cooperate with the doctor’s treatment, do not be careless, so as not to delay treatment.
