摘要 目的:分析自身免疫性胰腺炎(AIP)、胰腺癌(PC)的影像学表现,探讨对于AIP有价值的鉴别诊断征象。方法:回顾性搜集经临床确诊和手术病理证实的46例AIP和PC患者(每组各23例)的CT和MRI检查资料。分析上述两组病例的影像学表现,测量两组胰腺病灶及脾脏的CT值,对各种征象频数及所测CT值的差异进行统计学分析。结果:AIP典型影像学表现为弥漫性肿胀、腊肠样外观、纤维包膜、累及胆道系统(包括胆管壁增厚、胆总管向心性变窄、胆道系统轻度扩张),这些征象对鉴别AIP与PC有统计学意义(P<0.05)。AIP组与PC组在CT平扫、增强静脉期及延迟期胰腺病灶CT值、胰腺病灶CT值/脾脏CT值之间的差异有统计学意义(P<0.05)。结论:综合分析胰腺形态异常、胆道系统改变、胰周血管及淋巴结改变,大多数AIP能与PC进行鉴别。增强后CT值的测量对鉴别AIP与PC有一定的价值。 Objctive:To analyze imaging features of autoimmune pancreatitis AIP) and pancreatic carcinoma (PC) and to discuss the useful signs for the differential diagnosis. Methods:The study totally comprised 46 patients (23 with AIP, 23 with PC). Two Radiologists independently evaluated the imaging findings. Frequencies of findings and the mean CT at tenuation values of the lesions were compared between the two groups. Results: The typical imaging findings of AIP were diffuse enlargement, sausage shape, capsule like rim and the changes of bile duet system (including wall thickening, concen- tric stenosis and mild dilation of bile duet). The findings mentioned above were also useful for the differential diagnosis be- tween AIP and PC. There was statistical significant difference in CT attenuation values of the lesions and of the lesion/ spleen,in non-enhanced sean,venous phase and delayed phase, between AIP and PC groups (P^0.05). Conclusion: It can improve the differential diagnosis level between AIP and PC when analyzing the pancreatic affected area, bile duct and peripanereatic structures comprehensively. Quantitative analysis of the CT value is useful for the differential diagnosis between AIP and PC.
