Answer

Answer

Radiograph findings of involved peripheral joints are usually normal except for soft tissue swelling. An occasional patient with recurrent disease may show small bony erosions and joint space narrowing. Spine films show changes indistinguishable from ankylosing spondylitis. Blood work, including white blood cell (WBC) count, red blood cell (RBC) count, and erythrocyte sedimentation rate, usually reflect the intestinal disease.
