What does a hepatic space-occupying lesion mean?

Liver space-occupying lesions refer to abnormal tissues or structures that appear within the liver, occupying the position of originally normal liver tissue. These lesions may include benign tumors, malignant tumors, parasitic infections causing cysts or abscesses, as well as some stones or calcification foci. Common types of liver space-occupying lesions include hepatic hemangiomas, hepatic hamartomas, congenital liver cysts, cysts caused by hepatic echinococcosis, and nodular lesions of liver cirrhosis. Symptoms of liver space-occupying lesions may include abdominal pain, loss of appetite, general fatigue, abdominal masses, and jaundice. If these symptoms occur, timely medical examination at a hospital is recommended. Diagnosis of liver space-occupying lesions typically relies on imaging examinations such as ultrasound, CT, or MRI.
