After resection of a liver tumor, a re-discovery of a hypoechoic nodule with clear borders and still regular morphology indicates the presence of space-occupying changes in the liver, and the neatness of the borders does not indicate whether it is specifically a tumor recurrence or an inflammatory mass. Hypoechoic nodules mean that the density is higher than normal liver tissue, clear borders mean that the mass is clearly demarcated from normal tissue, and still regular morphology means that no obvious invasive changes are found. With this information, it is not possible to definitively determine whether it is a tumor recurrence or not, in addition to other conditions such as inflammatory changes, which require a puncture biopsy to make a final judgment. When nodules reappear in the liver after resection of a liver tumor, it is recommended to seek medical treatment in a timely manner in the hospital, and under the guidance of the doctor to carry out standardized examination and treatment to promote the development of the condition in a good direction and promote a good prognosis.
