A 69-year-old Caucasian female was referred to the Imaging Department for investigation of fever of unknown origin (FUO), fatigue for seven months, and recent onset of atypical chest pain. Laboratory tests revealed elevation of serum C-reactive protein levels and erythrocyte sedimentation rate.

Positron emission tomography with computed tomography fusion (PET-CT) with F18-fluorodeoxyglucose (FDG) was performed for the evaluation of FUO by excluding malignancy. The FDG images revealed markedly diffuse and circumferential increased uptake suggesting diffuse inflammatory process along the walls of the aorta and subclavian arteries.
