Systemic vasculitis encompasses a wide spectrum of inflammatory disorders involving blood vessels of varying size. The kidney is frequently involved because of a high degree of vascularity including blood vessels of varying diameter from large vessels to capillaries. Imaging investigations are often helpful to secure diagnosis of renal vasculitis, assess vascular complications and monitor response to treatment. Whereas angiography is no more performed in most cases it remains the gold standard in detecting renal artery microaneurysms. Cross sectional imaging modalities provide accurate assessment of vascular complications and occasionally diagnostic findings in vasculitis with intrarenal macroaneurysms. Finally, contrast-enhanced US is a new promising non-nephrotoxic modality with the potential to provide similar information compared to CT and MRI.
