Résumé
Objective To study CT findings of the intrahepatic bile duct and essential liver.Methods The clinical and CT material of the 113 cases of clonorchiasis were collected.The dilatation of Ⅱ,Ⅲ lever of intrahepatic bile duct were classified.Results 24 cases were slight degree dilated of the Ⅱ,Ⅲ lever bile duct,22 cases were light degree,31 cases were middle degree,36 cases were heavy degree.The light degree dilation of intrahepatic bile duct were found in whose clinical symptom and sign were not clear and obvious.The mid and heavy degree dilation of intrahepatic bile duct were found in those who has got abdominal pain,cold and fever,jaundice and complication.It was not relative between the calculus and dilation of intrahepatic bile duct.Dilation of intrahepatic bile duct with small piece of low density in liver essence accompany was found in 5 cases.Conclusion It would be the clonorchiasis if the minority small bile duct near liver membrane were dilated.Clinical symptom and sign are related to the dilative bile duct.CT findings of the small piece of low density essential liver and dilation of intrahepatic bile duct could be consider the inflammtory granuloma in the essential liver in clonorchiasis.
