Jejunal vasculitis in patient with rheumatoid arthritis: case report and literature review.

A 57-year-old man with rheumatoid arthritis presented severe abdominal pain symptomatic of panperitonitis. Computer tomography findings were consistent with vasculitis on the jejunum. Confirmatory angiography was conducted. Since abdominal vasculitis in rheumatoid arthritis is very rare, early diagnosis and treatment should be done according to clinical manifestation. In this case, high-dose steroid treatment was applied based on clinical manifestation, laboratory findings, and radiologic finding. After therapy, clinical manifestation and flare-up arthritis diminished.
