title: Abdominal microaneurysms in rheumatoid arthritis.
abstract: A 55-year-old man presented with systemic vasculitis complicating long-standing classical rheumatoid arthritis (RA). Digital and cutaneous vasculitis, together with widespread microaneurysms on both renal and coeliac arteries, were found. The simultaneous presence of these different patterns of vasculitic lesions in a single patient, affecting small as well as medium size vessels with aneurysm formation, emphasizes the value of angiographic studies in evaluating RA.
