7mm high echo in the right lobe of the liver may be the ultrasound imaging manifestation of intrahepatic bile duct stones, hepatic cavernous hemangioma, or hepatic metastases. 1. Intrahepatic bile duct stone: it can be related to biliary parasites, biliary tract infection, or cholestasis, etc. It is distributed in liver segments or lobes, and it can be shown to be hyperechoic in ultrasound examination. 2. Hepatic cavernous hemangioma: it is composed of many dilated abnormal blood sinusoids, which are filled with blood, and there is no clinical symptom when the tumor is small, and ultrasound as the first choice of examination reveals that the tumor manifests itself as a homogeneous hypoechoic mass, with clearer boundary, and the diameter ranges from 2mm to 20cm. 3. Liver metastasis: the tumor cells may reach the liver after hematogenous metastasis, or there may be direct invasion of tumor from neighboring organs, usually multiple, with diameters ranging from a few millimeters to more than 10mm, and may be calcified, and ultrasound may show multiple hyperechoic nodules in the liver, but it may also be hypoechoic nodules. After the detection of hyperechoic nodules in the right lobe of the liver, the nature of the lesion should be clarified in conjunction with relevant examinations in the laboratory or other imaging examinations, and appropriate treatment measures should be taken.
