PET/CT Reveals Localized Inflammation in the Temporal, Vertebral, and Lower Extremity Arteries in Giant Cell Arteritis.

ABSTRACT:18 F-FDG PET/CT is increasingly being used in the diagnosis of systemic vasculitis syndromes, especially large-vessel vasculitis. We present a case of giant cell arteritis in an 84-year-old man who exhibited large-vessel lesions in the periphery but none in the trunk. This case highlights the usefulness of PET/CT for revealing localized inflammation.
