title: Detection of asymptomatic aortic involvement in ANCA-associated vasculitis using FDG PET/CT.
abstract: Large vessel involvement in ANCA-associated vasculitis is very rare. We report here on the case of two patients with ANCA-associated vasculitis and asymptomatic aortic arch involvement diagnosed using FDG-PET/CT. Because aortic involvement in ANCA-associated vasculitis is a potentially life-threatening condition, its early detection can be crucial. FDG-PET/CT may also provide new insights into large vessel involvement as part of the spectrum of ANCA-associated vasculitis.
