For such cases, a preliminary inference should be made based on the blood flow of the nodule, whether the boundary is clear and the size of the nodule in the ultrasound. If the diagnosis cannot be confirmed, further CT scan or enhanced CT should be performed, and the nature of the nodule should be considered based on the results of the enhanced CT. If the patient has hepatitis B, further blood tests for alpha-fetoprotein will be needed to see if the alpha-fetoprotein is high. If the fetoprotein is high, combined with nodules and shadows in the liver area, close observation is needed at this time, and if necessary, a liver aspiration biopsy will be done to consider whether surgical treatment is needed as the next step based on the biopsy results. Patients should pay attention to check hepatitis B DNA, liver function and liver fibre tetralogy to determine whether the liver Child-Pugh grade is A or B. Generally, patients with grade B need active liver preservation treatment and consider surgery after grade A.
