Learning objectives

To review and demonstrate imaging features and role of interventional treatment of systemic vasculitis

Background

Vasculitis is relatively rare but can involve all visceral vasculature in whole body, which cause various symptoms depending on the size of the involved vessels and the target organs. Nonspecific symptoms such as fever or general fatigue can be the cause of delay of the correct diagnosis. Intestinal hemorrhage or peritoneal/retroperitoneal hemorrhage occurs with aneurysm formation and ulceration secondary to vasculitis, which can be managed by adequate interventional techniques. Percutaneous balloon angioplasty is one of the effective treatments of renovascular hypertension due to Takayasu’s arteritis....

Imaging findings OR Procedure details

Table of content and key findings1. Polyarteritis Nodosa Aneurysms or occlusions of the visceral arteries (especially renalartery)2. Microscopic Polyangiitis MPO-ANCA, Necrotizing glomerulonephritis3. Henoch–Schönlein purpura (anaphylactoid purpura) Deposition of IgA antibody, Purpura4. Takayasu arteritis Granulomatous inflammation affecting the aorta and its major branches, pulseless disease5. IgG4-related periaortitis Idiopathic sclerosing lesion, Elevated serum IgG4 concentration6. Collagen diseases (Behçet disease) Vascular Behçet (vasculitis of the vasa vasorum of the large arteries) 1. Polyarteritis NodosaDefinition Polyarteritis nodosa (PAN) is a representative disease of abdominal vasculitis. Pathologically it is a...

Conclusion

The comprehensive knowledge of imaging findings and interventional treatment of systemic vasculitis is important for the early diagnosis and treatment of the diseases, and can contribute for good outcome.
