Multiple low-density shadows in the liver may be benign or malignant, benign lesions do not need to worry too much, malignant lesions need to be dealt with in time. 1. Benign lesions: multiple low-density shadows in the liver indicate that there are occupying lesions in the liver. Benign occupying lesions in the liver include hepatic hemangioma, hepatic cyst, focal nodular hyperplasia, hepatic adenoma, inflammatory pseudotumor, etc., which do not need to be overly worried, and the occupying lesions are not big and asymptomatic, so they can be followed up on a regular basis. 2. Malignant lesions: malignant liver occupying lesions include cholangiocellular carcinoma, primary hepatocellular carcinoma, mixed hepatocellular carcinoma, etc., which may be metastatic from other parts of the body to the liver. Malignant lesions need timely treatment, and strive for surgical resection without delay. If multiple low-density shadows in the liver are found in the imaging examination, it is necessary to further improve the related examination such as enhanced CT or magnetic resonance, so as to clarify the nature of the disease at an early stage and to treat it at an early stage.
