Autoimmune pancreatitis (AIP) is an inflammatory disorder of pancreas. Two types have been identified: the diffuse and the focal or mass forming. Clinical presentation of AIP overlaps that of pancreatic cancer (PC). Sometimes serum IgG4 and CA 19-9 levels are unable to differentiate AIP from PC. Various series have shown that 5%-21% of resected pancreatic masses for suspected malignancy turned out to be AIP. Accurate diagnosis of focal AIP can avoid unnecessary surgeries. This paper elaborates the various imaging modalities useful in differentiating focal AIP from PC.
自身免疫性胰腺炎（AIP）是一种胰腺的炎症性疾病。已识别出两种类型：弥漫性和局灶性或肿块形成型。AIP的临床表现与胰腺癌（PC）重叠。有时血清IgG4和CA 19-9水平无法区分AIP和PC。各种研究系列表明，因疑似恶性肿瘤而切除的胰腺肿块中，有5%-21%最终被证实为AIP。准确诊断局灶性AIP可避免不必要的手术。本文阐述了有助于区分局灶性AIP和PC的各种影像学检查方法。
