Hepatic occupancies are generally benign and malignant lesions in the liver. Benign lesions include hepatic cysts, hepatic hemangiomas, hepatic cystic nodular hyperplasia, hepatic malignant lesions mainly refer to hepatocellular carcinoma, hepatic sarcoma, etc. Occupying lesions in the liver are sometimes not easily distinguishable on imaging, and need to be clarified by a puncture biopsy or by a combination of multiple imaging considerations, as well as specific tumor indicators such as methemoglobin, to reach consensus through a joint multidisciplinary consultation. Generally, liver occupancy is considered to require surgical treatment if it tends to be malignant, or surgical treatment if it tends to be benign, unless the mass is significantly enlarged, has symptoms of compression or causes abnormal liver function, and if malignant lesions are not excluded.
