Lobulated nodule 15mm*11mm in the upper left lobe and lower right lobe of the liver, the patient is considered to have hepatic nodule, the causes of hepatic nodule are benign hepatic nodule, inflammatory hepatic nodule and malignant hepatic nodule. 1. Benign hepatic nodule: for example, hepatic hemangioma, abdominal ultrasound or abdominal CT examination can show hepatic nodule, if the diameter of the nodule is small, usually pay attention to follow up; if the diameter of the hepatic nodule is large, it will cause compression effect on the tissues and organs around the liver, so it needs to be surgically resected to deal with the hepatic nodule. 2. Inflammatory liver nodules: for example, liver abscess is common in clinic, which can be manifested as liver nodules, and cephalosporin antibiotics (e.g., cefuroxime, etc.) can be chosen to carry out anti-infective treatment, and puncture and drainage of pus can be carried out if necessary. 3. Malignant liver nodules: for example, hepatocellular carcinoma, which is manifested as liver nodules on imaging. In early stage hepatocellular carcinoma patients, surgical resection of liver nodules or part of liver is important for prolonging the patients’ life and improving the quality of life. If you find liver nodules, you should go to the hospital in time to get a clear diagnosis, and do not be careless so as not to delay the treatment.
