Vasculitis syndromes: large vessel vasculitides and ANCA-associated vasculitides from a neuroradiologist’s perspective
摘要
The 2022 version of the American College of Rheumatology (ACR)-European Alliance of Associations for Rheumatology (EULAR) classification criteria for large vessel vasculitis and antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAVs) was substantially updated from the previous 1990 ACR criteria, with the role of diagnostic imaging significantly increased in accordance with the development of imaging modalities and expanding knowledge of the imaging findings. This review illustrates the basic characteristics of vasculitis syndromes in adults involving large vessels such as Takayasu arteritis, giant cell arteritis, and AAVs, with a brief introduction to the updated 2022 ACR/EULAR classification criteria, along with key clinical and imaging clues from a neuroradiologist’s perspective.
