A pseudo-focal lesion next to the falciform ligament of the liver is a pseudo-focal lesion found next to the falciform ligament of the liver and usually shows abnormal liver echogenicity or abnormal density. Pseudofoci next to the falciform ligament of the liver are not true liver occupying lesions, but rather a form of steatosis or due to a change in density in the surrounding area, which in some patients is due to a specific blood flow supply next to the liver. If the pseudo lesion next to the falciform ligament of the liver is found to be due to blood flow supply, it is a normal physiological reaction and does not require special treatment, but it usually does not disappear and regular review is sufficient. As for the phenomenon of fat infiltration next to the liver, the diet should be improved in time, and low-fat and low-cholesterol diet should be chosen as much as possible. If only the sickle ligament pseudo lesion of the liver is detected, it is necessary to consult a doctor in time, and diagnose and analyze through blood and urine amylase, chest CT, liver tissue biopsy to understand the cause and then target treatment.
