Limited intrahepatic calcification may be caused by intrahepatic bile duct stones, hepatic parasitosis, previous hepatic hemorrhage or injury. 1. Intrahepatic choledocholithiasis: It may be formed by calcification of part of the wall of the intrahepatic bile ducts. Ultrasound can show a strong echogenic mass and sound shadow similar to stones in the liver, and it usually does not lead to dilatation of the bile ducts. 2. Hepatic parasitosis: Hepatic parasitosis means that roundworms in the bile ducts die in the bile ducts and further calcify, which can form limited calcification of the liver. 3. Previous hepatic hemorrhage or injury: The patient has a history of hemorrhage or trauma to the liver, and the hemorrhaged or injured portion of the liver is gradually absorbed and calcified, resulting in limited calcification of the liver. This group of patients may not need to be treated for hepatic calcification. There are many other causes of intrahepatic limited calcification. If patients have uncomfortable symptoms, it is recommended that they go to the hospital for treatment in time to avoid adverse consequences.
