We report a series of FDG PET findings of a 69-year-old male patient with autoimmune pancreatitis (AIP) associated with extrapancreatic disease. The first FDG PET revealed diffuse uptake of FDG in AIP and retroperitoneal fibrosis (RF). The second FDG PET after cessation of steroid treatment indicated subsiding of disease activity in AIP, continuous disease activity in RF, and new extrapancreatic lesions, including enlargement of a right salivary gland, nephritis, and lymphadenopathy. The last FDG PET under steroid treatment revealed reduced FDG uptake in the above abnormal FDG uptake lesions. A series of these FDG PET findings suggest the usefulness of FDG PET for the diagnosis and monitoring of AIP associated with extrapancreatic autoimmune diseases.
我们报告了一名69岁男性自身免疫性胰腺炎（AIP）合并胰腺外疾病患者的一系列FDG PET检查结果。首次FDG PET显示AIP和腹膜后纤维化（RF）中FDG弥漫性摄取。停止类固醇治疗后的第二次FDG PET显示AIP疾病活动度减轻，RF疾病活动持续存在，以及新的胰腺外病变，包括右侧唾液腺肿大、肾炎和淋巴结病。类固醇治疗期间的最后一次FDG PET显示上述FDG摄取异常的病变中FDG摄取减少。这一系列FDG PET检查结果表明，FDG PET对诊断和监测合并胰腺外自身免疫性疾病的AIP有用。
