Aortic graft infection (AGI) is an uncommon but severe late complication of associated with vascular surgery. Early detection is important because of high mortality. Clinical findings often are nonspecific. Some of AGI patients present with FUO. A 67-year-old female received an endovascular aneurysm repair for abdominal aortic aneurysm. After 2 years of surgery she suffered from recurrent fever for 8 months and sometimes body temperature peaked at 40°C. Laboratory examinations show all are increased. Multiple modalities of imagine has been performed including x-ray, USG and CT. To find out the cause of FUO he was referred to perform 18F-FDG PET/ CT for further evaluation. The PET/CT images revealed the extent of the inflammation around grafts and the pelvic abscess, which helped to confirm the cause of FUO and establish the diagnosis of AGI. That indicates 18F-FDG PET/CT is a reliable modality for the FUO patients who has undergone endovascular aneurysm repair
