Ultrasonography report shows that the slightly hypoechoic nodule in the liver is more likely to be a hemangioma, and it may also be a tumor, focal fatty liver, intrahepatic bile duct stone and other conditions. 1. Hemangioma: it is a common benign neoplastic lesion, after diagnosis, it is usually followed up and observed without special treatment, but if the diameter of the lesion is too large and affects the surrounding tissues, it should be treated with surgery. 2. Tumor: Hepatocellular carcinoma or adenoma may appear as hypoechoic nodules, and the details should be further diagnosed according to other imaging examinations, such as enhanced CT, or pathological examination. 3. Focal fatty liver: there are usually localized fatty infiltration foci, mostly multiple foci, which are characterized by enhanced echogenicity of the infiltration foci, and may be in the shape of a mass. 4. Intrahepatic choledocholithiasis: stones are hyperechoic or strongly echogenic on ultrasound, usually present in the intrahepatic bile ducts, and are usually a few millimeters in size. This report shows that the size of 1.0cm×0.8cm is too large, so intrahepatic choledocholithiasis is unlikely. In order to make a clear diagnosis, it is recommended that further clarification be made by other imaging tests and pathologic examinations.
