Usefulness of fluorine-18 fluorodeoxyglucose PET/computed tomography in diagnosis of aortitis and treatment response evaluation in a patient with aortic prosthesis

We report the case of an 82-year-old man with aortic prosthesis inflammation in whom fluorine-18 fluorodeoxyglucose (FDG) positron emission tomography/computed tomography has been useful in the detection of the cause of fever of unknown origin. We also describe the correlation between decrease of FDG uptake in the vascular prosthesis after treatment and clinical improvement with normalization of the serological levels of inflammatory markers
