Cricoarytenoid arthritis in a patient with ankylosing spondylitis

A 50-year-old woman with a 27-year history of ankylosing spondylitis developed cricoarytenoid joint arthritis that was indicated by hoarseness, sore throat, and vocal cord fixation. This unusual manifestation of ankylosing spondylitis responded to treatment with moderate doses of prednisone, but it recurred when the cortiocosteroid therapy was discontinued.
