自身免疫性胰腺炎(autoimmune pancreatitis,AIP)是由自身免疫介导一种特殊类型的慢性胰腺炎,主要表现为胰腺肿大和胰胆管狭窄,临床上经激素治疗可痊愈。此病易误诊为胰腺肿瘤,常造成不必要的手术治疗。其影像表现具有一定的特征性,认识其影像表现对于正确的诊断和治疗极其重要[1]。本研究回顾性总结了经病理或临床治疗证实的7例AIP患者的MR影像学特点,为临床正确诊断提供帮助。
Autoimmune pancreatitis (AIP) is a type of chronic pancreatitis mediated by autoimmunity. It mainly shows pancreatic enlargement and pancreaticobiliary stenosis, which can be clinically cured by hormone therapy. The disease is misdiagnosed as pancreatic cancer, often resulting in unnecessary surgical treatment. Its imaging performance has a certain characteristic, to recognize its imaging performance for the correct diagnosis and treatment is extremely important [1]. This study retrospectively reviewed the MR imaging features of 7 AIP patients confirmed by pathology or clinical treatment, which could be helpful in the correct diagnosis.
