 There are increasing data demonstrating the role of 18F-flourodeoxyglucose positron emission tomography with computerized tomography fusion (18F-FDG PET/CT) in the diagnosis of large vessel vasculitis, including Takayasu arteritis and giant cell arteritis. We report a case of large vessel vasculitis detected on 18F-FDG PET/CT; a 32-year-old woman with history of Non Hodgkin Lymphoma, admitted with fever of unknown origin (FUO) of 2-months duration and asthenia. To exclude FUO of malignancy, in the suspect of NHL relapse, 18F-FDG PET/CT imaging was performed. The images demonstrated significant 18F-FDG uptake in aortic arch and no signs of NHL relapse. This case report supports the role of 18F-FDG PET/CT as a useful and noninvasive tool in diagnostic evaluation of patient with FUO, both by excluding a malignant etiology and providing information about other possible causes such as inflammation, including vasculitis. 18F-FDG PET/CT is very useful in the early diagnosis of active inflammation including vasculitis and provides timely information for appropriate therapy.
