B-ultrasound liver parenchyma echo enhancement

What causes the enhanced echo of liver parenchyma on ultrasound? In fact, enhanced echogenicity of the liver parenchyma can occur in many diseases and is a common phenomenon. For example, intrahepatic calcification, hemangioma,

This situation may occur in cases of intrahepatic bile duct stones, etc. So in principle, if this is the only issue, it is generally considered not a big deal and no special attention is needed. If accompanied by other symptoms, it needs to be taken seriously.

Intrahepatic calcifications are "scars" formed after inflammation of liver parenchymal cells. They are generally not a serious problem. Some patients may feel stuffy and bloated in the liver area, just like patients with intrahepatic bile duct stones. If diagnosed, no treatment is generally required. Calcification spots in the liver may be partial calcification of the intrahepatic bile duct wall. It is mostly caused by inflammation, tuberculosis, etc. It may also be caused by intrahepatic calcification foci and fibrotic scars after local necrosis of liver tissue. It is the most important differentiation from intrahepatic bile duct stones. With the popularization and development of B-ultrasound examination technology in hospitals at all levels, many healthy people are found to have strong echo masses and acoustic shadows similar to stones in the liver during physical examinations, and many people mistakenly believe that they have intrahepatic bile duct stones.

Intrahepatic bile duct stones are a type of bile duct stones , which refer to stones in the bile ducts above the confluence of the left and right hepatic ducts. It can exist alone or coexist with extrahepatic bile duct stones. Usually bilirubin stones. Intrahepatic bile duct stones are often accompanied by extrahepatic bile duct stones, which may lead to bile duct obstruction, local infection and secondary bile duct stenosis, making it difficult for the stones to be discharged on their own and causing the disease to persist. This disease can cause serious complications and is an important cause of death from benign biliary diseases.

Most hemangiomas are cavernous hemangiomas, a common benign liver tumor that can occur at any age, but often presents symptoms in adults, mostly in women. Hemangiomas are the most common benign tumors in the liver. Most cases can be diagnosed before surgery, and the vast majority are asymptomatic. A few may experience discomfort in the liver area due to large tumors. If there is a tendency to increase in size, or if it is located under the liver capsule, there may be massive bleeding and life-threatening, and treatment should be sought as soon as possible. Tumors can be found in any part of the liver, often under the capsule, and are mostly single (about 10% are multiple). The tumor diameter is usually less than 4 cm, but can be as small as a few mm, and some can be as large as 30 cm. The surface of the tumor is dark red or purple, with a capsule on the outside and a spongy cross-section. Thrombosis and scarring can sometimes be seen inside the hemangioma, and calcification is occasionally present. Under the microscope, hemangioma is a network of interstitial spaces formed by vascular tubes with flat endothelial cells of different sizes on the inner wall, which contain red blood cells and sometimes fresh organized thrombi. The tumor is clearly demarcated from the surrounding tissues.
