Vasculitis occurs in a number of disorders and may be associated with musculoskeletal manifestations. Although arteriography can reveal characteristic alterations in these disorders, radiographic abnormalities are unimpressive. In polyarteritis nodosa, periosteal bone formation may be seen, particularly in the lower extremity. Articular abnormalities in giant cell (temporal) arteritis relate to its association with polymyalgia rheumatica and include soft tissue swelling and osteoporosis. In Henoch-Schönlein purpura and erythema nodosum, joint effusions are the only characteristic radiographic abnormality. Cryoglobulinemia is occasionally accompanied by cystic and erosive lesions of bone in both the axial and the appendicular skeletons. The candidate will learn the mechanics of putting together an electronic poster presentation in lecture type format. This will be an official peer-reviewed publication. The publication will be a favorable addition to the candidate's CV. The candidate will be the first author, and I am the second author. A candidate is not limited to completing one project. He/she can do as many as they like! (There are always topics to teach about) The candidate, myself, King's College Hospital Department of Radiology and King's College all benefit from this publication.
