Cancer is a malignant disease caused by a functional malfunction of the mechanisms within the body’s tissues that control cell growth and proliferation. The cells grow and divide at a much higher rate than normal cells and can often invade surrounding normal tissues through metastasis or even move to other parts of the body through the body’s circulatory or lymphatic system. Both hepatocellular and cholangiocellular hepatocellular carcinomas may form irregularly bordered soft tissue masses within the liver, with multiple hypodense shadows observed on liver imaging.
But in addition, diseases such as fatty liver, liver cysts, and liver abscesses may form this contrast. In general, if the hypointense shadow is lamellar and relatively limited in distribution, it is likely to be caused by a heterogeneous fatty liver. However, if the hypointense shadow appears as a relatively regular round or round-like shape with clear borders, it is clinically considered to be a liver cystic lesion. If the boundary is unclear, and the shape is not very regular, and there is no pain, abdominal distension, general weakness, yellow and thin face, etc., it is likely to be a liver abscess.
