The imaging manifestations of papillary intrahepatic bile duct carcinoma include CT and magnetic resonance manifestations, which are as follows. 1. CT manifestation: nodules or masses with variable morphology in the dilated bile ducts, which can not be shown if the tumor size is small and only shows dilatation of intrahepatic bile ducts. Due to the richer blood supply of papillary carcinoma of bile duct, its enhancement is more obvious than that of papilloma, which suggests that enhancement is helpful for the differential diagnosis of benign and malignant tumors. 2. Magnetic resonance imaging (MRI): it is mostly manifested as nodules or masses with variable morphology in the bile ducts, accompanied by obvious dilatation of the intrahepatic and extrahepatic bile ducts. Scanning is equal or slightly long T1, slightly long T2 signal, local continuation in the bile duct wall, enhancement is uneven and mild to moderate enhancement, relatively obvious in the portal vein phase, the border becomes clearer than the scanning. When intrahepatic bile duct papillary carcinoma is suspected, it is necessary to consult a doctor in time, complete relevant examinations and carry out standardized treatment under the guidance of doctor.
