目的:探讨自身免疫性胰腺炎(AIP)的临床特点。方法:总结1例AIP患者临床表现、实验室、影像学、病理学检查及治疗情况。结果:患者,男,55岁,以上腹部不适疼痛伴黄疸2个月就医,误诊胰腺癌。经血清IgG 1 840 mg/dl、内镜逆行胰胆管造影(胰管头部线样不规则狭窄)、CT(胰腺体积增大,胰头明显)、MRI(胰腺弥漫异常改变)、病理学(胰腺间质纤维增生伴淋巴细胞浸润)证实为AIP,激素治疗反应好。结论:AIP临床表现缺乏特异性,影像学、血清学和胰腺病理学是诊断AIP的重要手段。
Objective: To investigate the clinical features of autoimmune pancreatitis (AIP). Methods: The clinical manifestations, laboratory, imaging, pathological examination and treatment of 1 patient with AIP were summarized. Results: The patient, male, 55 years old, suffered from abdominal discomfort and jaundice for 2 months and was misdiagnosed as pancreatic cancer. Serum IgG1 840 mg / dl, endoscopic retrograde cholangiopancreatography (irregular linear stenosis of pancreatic duct), CT (pancreatic enlargement, clear head of pancreas), MRI (abnormal diffuse pancreas), pathology Pancreatic interstitial fibrosis with lymphocytic infiltration) confirmed as AIP, hormone response to treatment. Conclusion: The clinical manifestations of AIP are lack of specificity. Imaging, serology and pancreatic pathology are important methods for diagnosis of AIP.
