title: Recurrent Stenosis of the Ileum Caused by Rheumatoid Vasculitis.
abstract: A 65-year-old man with a 20-year history of rheumatoid arthritis was transferred to our hospital due to a second episode of intestinal obstruction, a fever, and joint pain within the previous 6 months. He had an extremely high rheumatoid factor level and decreased complement levels. Abdominal computed tomography, a small bowel series, and small intestinal endoscopy revealed severe ileal stenosis. Resection of the stenotic lesion was performed, and a histopathological examination revealed vasculitis. Rheumatoid vasculitis was diagnosed, and the patient began treatment with prednisolone and methotrexate, which improved his condition. Rheumatoid vasculitis is a rare, but possible cause of recurrent bowel obstruction.
