There is a difference between intrahepatic calcified foci and intrahepatic bile duct stones as follows.
1. location: intrahepatic calcified foci refer to calcium deposits inside the liver and liver parenchyma, whereas intrahepatic bile duct stones refer to bile ducts inside the liver and then stones growing inside the bile ducts, with deeper lesion locations.
2. imaging: intrahepatic calcified foci are seen by imaging as strong echogenic or high-density images similar to stones, whereas intrahepatic bile duct stones can also be seen as stones and blockage of the proximal bile duct dilatation.
3. treatment: intrahepatic calcified foci generally have no effect on the body and require no treatment, whereas intrahepatic bile duct stones require surgery to remove the stones.
