Symptoms of hepatic hypodense foci are related to their size, location, and nature, and may be accompanied by clinical symptoms such as nausea and vomiting, obstructive jaundice, and lethargy and fatigue. 1. Size and location. Regardless of benign or malignant, as long as the size of the lesion is so large that it obviously compresses the surrounding tissues, the corresponding compression symptoms will easily appear. For example, nausea and vomiting will occur when the gastrointestinal tract is compressed, dyspnea will occur when the lungs are compressed, and obstructive jaundice will occur when the bile ducts are compressed. 2. Nature. If the benign lesion is not large and does not compress the surrounding tissues, it usually does not show obvious symptoms. Malignant lesions such as primary hepatocellular carcinoma or metastatic hepatocellular carcinoma may show typical malignant manifestations, such as rapid weight loss within a short period of time, weakness, poor appetite, and persistent low-grade fever of unknown cause. After checking out the low density foci of the liver, one should consult a doctor in time, and improve the relevant examination under the doctor’s guidance to clarify the specific situation, and then do individualized treatment.
