CONTEXT
Autoimmune pancreatitis is a rare disorder characterized by the systemic deposition of IgG4 plasma cells. Extrapancreatic manifestations of autoimmune pancreatitis depend on the site of plasma cell deposition. The most common extrapancreatic site of involvement is the bile duct followed by the retroperitoneum and kidneys.
CASE REPORT
We report a case of a patient with autoimmune pancreatitis and renal lesions who underwent MRI prior to and after corticosteroid therapy.
CONCLUSION
We emphasize the role of diffusion weighted imaging (DWI) and apparent diffusion coefficient (ADC) findings on MRI in evaluating the response to steroid therapy.
背景
自身免疫性胰腺炎是一种罕见的疾病，其特征是IgG4浆细胞在全身沉积。自身免疫性胰腺炎的胰腺外表现取决于浆细胞沉积的部位。最常见的胰腺外受累部位是胆管，其次是腹膜后和肾脏。
病例报告
我们报告一例自身免疫性胰腺炎合并肾脏病变的患者，该患者在接受皮质类固醇治疗前后均接受了MRI检查。
结论
我们强调MRI上的扩散加权成像（DWI）和表观扩散系数（ADC）结果在评估类固醇治疗反应中的作用。
