胰腺结石或钙化的影像学分析及其鉴别诊断

Imaging findings and differential diagnosis of pancreatic stones or calcinosis

目的 :探讨胰腺结石或钙化的影像学特征及其鉴别诊断价值。方法 :收集我院 1991～ 2 0 0 1经手术证实胰管结石病人 18例并分析其影像学特征。结果 :(1)胰腺结石沿胰管走行伴胰管高度扩张 ,以胰头部最大 ,常呈斑块样 ,周围可分布粟粒样小结石 ;(2 )CT对胰腺结石显示率均为 10 0 % ,且CT可显示胰腺结石引起的并发症。 (3)胰腺结石与胰腺内钙化在病理上是有区别的。结论 :(1)B超应作为胰腺结石首选 ,CT是目前各种影像检查中的最佳方法 ,对确诊和显示胰腺结石的并发症以及设计手术方案有重要意义 ;(2 )一旦确诊应争取早期手术 ,可延缓一些并发症的发生。

Objective:To evaluate the imaging findings and differential diagnosis of pancreatic stones(PS).Methods:18 patients hospitalized undergoing surgical therapy during 1991-2001 were studied retrospectively,and their imaging findings analyzed.Results:(1)PS were along with pancreatic duct in company with pancreatic duct high dilatation and the maximum PS were in pancreatic head.(2)PS was seen 100% on CT.CT can find PS combined with other complications.(3)PS are different from pancreatic calcinosis.Conclusions:(1)Ultrasonography was the first choice for cxamination.It is valuablc to usc CT to cstablish diagnosis and display complications for designing preoperation strategy.(2)Patient with definite diagnosis of PS should undergo early operation.
