【摘要】 目的探讨胰腺分支胰管型导管内乳头状黏液瘤的MRI诊断及鉴别诊断。方法回顾性分析经手术病理证实的9例胰腺分支胰管型导管内乳头状黏液瘤的临床及MRI表现。结果 9例胰腺分支胰管型导管内乳头状黏液瘤患者年龄56~78岁,平均66.3岁,其中男性4例,女性5例,8例单发,1例多发。胰腺分支胰管型导管内乳头状黏液瘤的MRI表现呈多房囊样表现4例、呈分叶状3例、呈孤立单囊状2例;5例囊内见轻度强化壁结节。MRCP及薄层图像上能够显示胰腺分支胰管型导管内乳头状黏液瘤的囊与主胰管相通。结论 MRI在胰腺分支胰管型导管内乳头状黏液瘤的诊断与鉴别诊断中具有非常重要的价值。更多还原

【Abstract】 Objective To analyze MR diagnosis and differential diagnosis of branch duct-intraductal papillary mucinous neoplasms in pancreas(BD-IPMNs).Methods Clinical and MRI features of 9 cases with pathologically proved BD-IPMNs were analyzed retrospectively.Results A total of 9 patients(4 males and 5 females,aged 56 to 78 years,mean 66.3years) with histopathologically proved BD-IPMNs were enrolled in the study,including that 8 tumors were single and 1was multiple.In MRI and MRCP,the BD-IPMNs presented with multiloculated cystic tumor in 4 cases(4/9),with lobular shape in 3 cases(3/9),with single cystic tumor in 2 cases,with mural nodules showed slight enhancement in 5 cases of lesions(5/9).MRCP and thin-layer images distinctly revealed the traffic between the mainpancreatic duct and lesions in 9cases of BD-IPMNs(9/9).Conclusion MRI play an important role in diagnosis and differential diagnosis of BD-IPMNs.更多还原
