Abstract:
Objective:To analyze the magnetic resonance imaging(MRI) characteristics of hepatic mucinous cystic neoplasm (MCN) and cyst-forming intraductal papillary neoplasm of the bile duct (IPNB), aiming to improve physicians′ ability of diagnosis and differential diagnosis of these 2 diseases.Methods:From June 1, 2010 to October 20, 2023 at Zhongshan Hospital, Fudan University and People′s Hospital of Rizhao, the clinical data and MRI characteristics of 96 patients with hepatic MCN(58 cases, hepatic MCN group) or cyst-forming IPNB(38 cases, cyst-forming IPNB group) who underwent surgical resection with pathological confirmation were retrospectively analyzed. The clinical data included gender, age, etc. The MRI characteristics included lesion characteristics such as septum, hemorrhage, and calcification, etc. Chi-square test or Fisher′s exact probability method was used for statistical analysis.Results:The proportion of female, the presence of septatum, hemorrhage and calcification of the hepatic MCN group were all higher than those of the cyst-forming IPNB group (91.4%(53/58) vs. 60.5%(23/38), 89.7%(52/58) vs. 34.2%(13/38), 31.0%(18/58) vs. 5.3%(2/38), 12.1%(7/58) vs. 0(0/38)); the proportion of lesions with invasion, upstream bile duct dilation, mural nodule, downstream bile duct dilation, hepatic lobe atrophy, and communicated with the bile duct of the hepatic MCN group were all lower than those of the cyst-forming IPNB group (10.3%(6/58) vs. 55.3%(21/38), 20.7%(12/58) vs. 89.5%(34/38), 8.6%(5/58) vs. 94.7%(36/38), 0(0/58) vs. 65.8%(25/38), 0(0/58) vs. 10.5%(4/38), 0(0/58) vs. 100.0%(38/38)); and the differences were statistically significant ( χ2gender=13.25, χ2septatum=32.28, χ2invasion=22.92, χ2upstream bile duct dilation=43.52, others were all Fisher′s exact probability method; all P<0.05). Conclusion:The MRI characteristics of hepatic MCN and cyst-forming IPNB have certain characteristics and differences, and MRI is helpful for the diagnosis and differential diagnosis of the 2 diseases.
