Liver occupancy may be caused by diseases such as hepatic hemangioma, hepatic cysts, and liver cancer. Hepatic space occupation, also known as liver occupying lesion, is a manifestation under imaging examination, suggesting the presence of masses on the liver, including benign tumors such as hepatic cysts and hepatic hemangiomas, or malignant tumors such as hepatocellular carcinoma, and if it is not clear about the nature of the mass, puncture biopsy can also be considered to clarify the benignness and malignancy of the mass, which will help in further diagnosis and treatment. Therefore, it is not true that liver space-occupying lesions must be cirrhosis, but cirrhotic patients may have liver space-occupying lesions if they have cirrhotic nodules. It is recommended to go to the hospital when liver occupying lesions appear, and ask the doctor to make a judgment and clarify the cause of the disease.
