A single intrahepatic calcified foci located in the s7 segment is defined as a stone like strong echogenic shadow in the upper right posterior lobe of the liver on ultrasound or CT images, which is often associated with intrahepatic choledocholithiasis, inflammatory, neoplastic calcified foci, and parasitic infections, among other causes. There are many reasons for the formation of intrahepatic calcified foci, with intrahepatic bile duct stones being the most common factor, followed by chronic inflammation or trauma within the liver, parasitic infections, and liver tumors. In addition, congenital developmental abnormalities within the liver have calcified foci formed within the liver during fetal life, but the detection rate is not high. Intrahepatic calcified foci are generally scarring left on the liver after healing of liver lesions. If they are not accompanied by other diseases and have normal liver function, they can only indicate simple intrahepatic calcified foci, which do not affect life.
