Abstract:
Objective To describe the MRI features and pathologic findings of biliary cystadenocarcinoma(BCAC)and to assess the diagnostic value of MRI in those tumors.Methods Five cases of BCAC were collected.All cases were proved by pathology.Non-enhanced and multiphase-enhanced MRI were performed in all cases.MRCP were performed in two cases.The MRI features of the five cases were reviewed retrospectively and correlated with pathologic findings.Results Histological evidence demonstrated five cases of BCAC.Four cases were solitary,whereas the other case was multifocal.All cases were solid and cystic lesions.Two cases were unilocular,whereas the other three cases were multilocular. Multiple mural nodules and irregular thickening cystic walls were presented in all cases.The cystic parts of the lesions were homogeneous in signal intensity and showed no enhancement after contrast administration in the five BCAC.Septa were present in three BCAC with multilocular cyst.On MRCP the bile duct dilatation was found in two BCAC.Conclusion MRI can reveal the characteristic findings of BCAC and accurate preoperative diagnosis can be made.
