aIn LVV, ultrasound showing halo sign, angiography showing vascular wall thickening, enhancement, stenosis, occlusion, or aneurysms, or PET showing FDG uptake of the aorta or its major branches. In PAN, angiography showing multiple microaneurysms. In BD, angiography showing thrombosis, vascular wall thickening, enhancement, stenosis, occlusion, or aneurysms
bIn LVV, presence of arteritis, often granulomatous, affecting the aorta or its major branches. In PAN, necrotizing arteritis of medium or small arteries. In AAV, necrotizing vasculitis predominantly affecting small vessels: in EGPA eosinophil-rich and necrotizing granulomatous inflammation, in GPA necrotizing granulomatous inflammation, and in MPA necrotizing inflammation with absence of granulomas. In CV, vasculitis affecting small vessels with cryoglobulin immune deposits
