This is a case of a 54 years old woman with fever of unknown origin. Physical examination showed nothing remarkable. Chest radiographs, abdominal ultrasound examination (US) and chest-abdominal-pelvic CT, showed segmental thickening of the wall of the aorta. On admission, the C-reactive protein level and the erythrocyte sedimentation rate were elevated. (18)Fluoro-fluorodeoxyglucose-positron emission tomography ((18)F-FDG-PET/CT) showed increased uptake of the aorta wall and its main branches that could be indicative of arteritis. The temporal artery biopsy was negative for giant-cell arteritis. The patient responded well to prednisolone treatment. A second (18)F-FDG-PET/CT scan showed great improvement. (18)F-FDG-PET/CT scan early indicates arteritis of the great vessels that in this case was considered to be TA and contributes in monitoring disease activity.
这是一例54岁不明原因发热的女性病例。体格检查未发现明显异常。胸部X线片、腹部超声检查（US）及胸腹部盆腔CT显示主动脉壁节段性增厚。入院时，C反应蛋白水平和红细胞沉降率升高。（18）氟脱氧葡萄糖正电子发射断层扫描（（18）F-FDG-PET/CT）显示主动脉壁及其主要分支摄取增加，提示可能存在动脉炎。颞动脉活检巨细胞动脉炎结果为阴性。患者对泼尼松龙治疗反应良好。第二次（18）F-FDG-PET/CT扫描显示有显著改善。（18）F-FDG-PET/CT扫描可早期提示大血管动脉炎，在本病例中考虑为颞动脉炎，并有助于监测疾病活动。
