摘 要: | 目的:研究自身免疫性胰腺炎(AIP)的影像学特征。方法:回顾性分析15例符合2008亚洲诊断标准的AIP患者的CT和MRI影像学资料,总结胰腺及胰腺外的影像学表现。结果:10例AIP表现为胰腺弥漫性增大,5例AIP表现为胰腺局部肿大。病灶区在T1WI上信号明显降低,在T2WI上信号轻度升高,15例均见渐进性延迟强化,3例见“鞘膜征”,9例AIP胆总管胰腺段的狭窄,3例ERCP均示胰管不规则狭窄,2例双肾多发节结影。结论:AIP具有一定特征性影像学表现;影像检查是诊断AIP的必要手段。

Abstract: | Objective:To investigate the radiologic characteristics of autoimmune pancreatitis(AIP).Method: The radiological data of 15 AIP patients met the Asia diagnostic criteria of AIP in 2008 were retrospectively reviewed, the radiologic characteristics of extrapancreatic and intrapancreatic lesions was described.Result: CT and MRI showed diffuse swelling of the pancreas in 10 cases and focal enlargement in 5 cases. The swollen pancreas was hypointense on T1WI and mildly hyperintense on T2WI, 15 paitients appeared enhancement on delayed phase. A capsule-like rim was showed in 3 cases. Narrowing of the intrapancreatic portion of common bile duct were found in 9 cases, and ERCP showed diffuse and irregular narrowing of the main pancreatic duct in 3 cases. Low density nodular foci in double kidneys were seen in 2 cases. Conclusion: AIP has certain characteristics of typical imaging feature ,imaging examinations play an important roles in the diagnosis of AIP. |
