Abstract:
Objective: To analyze CT and MRI manifestations of mucinous cystic neoplasms (MCN) and cyst-forming intraductal papillary neoplasms of the bile duct (IPNB). Methods: Clinicopathological and imaging data of 25 MCN patients (MCN group) and 16 cyst-forming IPNB patients (IPNB group, including 10 invasive IPNB patients and 6 noninvasive IPNB patients) confirmed pathologically were retrospectively analyzed. Results: There were significant differences of bile duct dilation, communication with lesions and bile ducts, mural nodules between MCN group and IPNB group (all P<0.001).No difference was found in lesions diameter, location, shapes, intracystic hemorrhage nor ADC value between the two groups (all P>0.05). Only lesion diameter was significantly different between invasive and noninvasive IPNB (P=0.032). Conclusion: CT and MRI features of MCN and cyst-forming IPNB are similar. Dilated bile ducts, communication between dilated bile ducts and mural nodules in lesions have high value in differential diagnosis of these two diseases.
