Abstract Objective: To explore the MRI features of intrahepatic bile duct hamartoma in order to improve the understanding and diagnosis method of the disease. Methods: A total of 13 adult patients diagnosed by both hospital of intrahepatic bile duct hamartomas were enrolled and MRI features were analyzed systematically. Results: Three cases were confirmed by puncture. All patients were diffuse multiple lesions, 12 cases of diffuse lesions of liver two lobes, 1 case of diffuse distribution in the right lobe of liver; with uniform signal and unequal in size. The majority of lesions were less than 10 mm, showed as long T1 and long T2 cystic signal, DWI signal was low, no enhancement on contrast-enhanced imaging, MRCP showed lesions along the biliary tree and without connection between biliary tree. Conclusion: The liver bile duct hamartoma in MRI scans have specific performance, through the understanding of these signs to improve the diagnosis and different diagnosis of the disease.
