Abstract
We report the fluorodeoxyglucose positron emission tomography FDGPET/computed tomography CT findings of autoimmune pancreatitis AIP associated with idiopathic retroperitoneal fibrosis A 69yearold male patient was admitted to our hospital with obstructive jaundice Six months prior to this admission he was treated with steroid therapy for retroperitoneal fibrosis Laboratory data showed that elevated Tbil Creactive protein amylase and immunoglobulin 4 and antinuclear antibodies were positive Clinical history laboratory data CT image and magnetic resonance imaging led to a diagnosis of autoimmune pancreatitis To investigate the inflammatory activity FDGPET/CT was undertaken FDGPET/CT demonstrated diffuse intense FDG uptake in the enlarged pancreas and diffuse mild uptake in the region of the abdominal aortabilateral iliac arteries A dilated right renal pelvis and upper ureter corresponding to hydronephrosis probably caused by retroperitoneal fibrosis were shown An FDGPET/CT was useful to evaluate inflammatory activity and morphological imaging and supported our diagnosis of AIP and retroperitoneal fibrosis
