Is intrahepatic bile duct dilatation mainly a tumor or a stone

Intrahepatic bile duct dilatation may be tumor or stone.

If the patient's intrahepatic bile duct dilatation is accompanied by cough, hemoptysis, loss of appetite, etc. of unknown cause, it is suggested that it is related to tumor. Because the patient's tumor is constantly increasing, it may compress the bile duct and hinder the normal flow of bile, causing dilatation. However, if the patient does not accompany the above phenomenon, pain, abdominal distension, etc., may be caused by stones. Stone patients due to bile duct stimulation, may produce more mucus, then accumulate in the bile duct, affect the function of bile duct, prone to dilatation.
