目的 分析自身免疫性胰腺炎(AIP)与小胰腺癌的CT、MRCP影像学征象的差异,提高对AIP的认识及诊断的准确率.方法 回顾性分析符合2008年AIP亚洲诊断标准的24例AIP及病理证实的25例小胰腺癌(≤2 cm)的影像学资料,从胰腺的形态改变、密度及强化方式、胰管及胰周、胰外表现等方面进行比较,采用×2检验或确切概率法行统计学处理.结果 在AIP和小胰腺癌组间,肿块部位、远端胰腺萎缩、肿块持续强化、胰管“截断征”、“鞘膜征”及肾脏受累征象差异具有统计学意义(x2 =9.010、10.506、15.288、8.688、6.292和4.966,P＜0.05),但是只有远端胰腺萎缩和肿块持续强化征象在局限性AIP与小胰腺癌组间差异具有统计学意义(P＜0.05).结论 弥漫性AIP的影像学改变具有特异性,与小胰腺癌容易鉴别诊断,但局灶性AIP与小胰腺癌鉴别诊断价值有限.
目的 分析自身免疫性胰腺炎(AIP)與小胰腺癌的CT、MRCP影像學徵象的差異,提高對AIP的認識及診斷的準確率.方法 迴顧性分析符閤2008年AIP亞洲診斷標準的24例AIP及病理證實的25例小胰腺癌(≤2 cm)的影像學資料,從胰腺的形態改變、密度及彊化方式、胰管及胰週、胰外錶現等方麵進行比較,採用×2檢驗或確切概率法行統計學處理.結果 在AIP和小胰腺癌組間,腫塊部位、遠耑胰腺萎縮、腫塊持續彊化、胰管“截斷徵”、“鞘膜徵”及腎髒受纍徵象差異具有統計學意義(x2 =9.010、10.506、15.288、8.688、6.292和4.966,P＜0.05),但是隻有遠耑胰腺萎縮和腫塊持續彊化徵象在跼限性AIP與小胰腺癌組間差異具有統計學意義(P＜0.05).結論 瀰漫性AIP的影像學改變具有特異性,與小胰腺癌容易鑒彆診斷,但跼竈性AIP與小胰腺癌鑒彆診斷價值有限.

Objective To increase the awareness of autoimmune pancreatitis (AIP) and correct diagnosis rate of AIP by investigating radiologic characteristic of AIP and small pancreatic cancers.Methods The clinical data and radiologic imaging of 24 AIP patients who met the Asia diagnostic criteria of AIP in 2008 and 25 cases of pathologically condirmed small pancreatic cancer were retrospectively reviewed.All imaging findings were reviewed,especially on the shape,enhancement patterns of mass,pancreatic ducts,peripancreatic and extra-pancreatic manifestations. Chi-square test and Fisher test were used for statistical analysis.Results The imaging signs,including location of masses,distal pancreatic atrophy,enhancing mass during portal phase,truncated duct sign of pancreatic duct,capsule-like rim and renal involvement,was significantly different between AIP and small pancreatic cancer ( x2 =9.010,10.506,15.488,8.688,6.292 and 4.966 respectively,P ＜0.05 ).But only two signs,distal pancreatic atrophy and enhancing mass during arterial and portal phase,were statistically different between local AIP and small pancreatic cancer (P ＜0.05).Conclusions The typical imaging features of diffuse AIP is distinct and helpful for the differential diagnosis of AIP from small pancreatic carcinoma,but there is limited value in the differential diagnosis between local AIP and small pancreatic cancer.
