Vasculitides are a heterogeneous group of disorders that share the common feature of inflammation of the blood vessel wall. Vasculitis can be a systemic or localized process and depending on the disorder can affect large, medium, or small vessels. Vascular physicians including interventional radiologists often may be involved early in these cases before the establishment of a diagnosis as these patients may present with manifestations attributable to occlusive vascular syndromes. In this article, we discuss the presenting signs and symptoms of patients with vasculitis as well as laboratory and imaging studies required to further evaluate these disorders and treatment options, which include interventional as well as noninterventional options.
