Intrahepatic strong echogenic nodule is a common description in ultrasound examination, which is considered to be intrahepatic calcified foci, hepatic bile duct stones, liver tumors and so on. 1. Calcified foci in liver:Inflammation, trauma, parasites and other causes of liver cell necrosis, calcium salts can be deposited in the local necrotic tissue, forming calcified foci, the density is higher than the hepatocyte tissue, presenting strong echogenic nodules in the liver. 2. Hepatic bile duct stones: the etiology of the formation of hepatic bile duct stones is more complex, mainly associated with bacterial infection, parasitic infection, bile retention and other factors, the main component of the stone is calcium salts, in the ultrasound can be seen in the strong echogenic nodules. 3. Liver tumors:Liver tumors caused by various reasons, common causes include viral infections, cirrhosis, aflatoxin, etc. Liver tumors are hard and more dense than normal liver tissue, and they can show strong echogenic nodules in ultrasound. Strongly echogenic nodules in the liver may also be due to other causes, please consult the doctor as soon as possible to avoid delaying the condition.
