title: Rheumatoid arthritis simulating other lesions.
abstract: Radiographs of patients with rheumatoid arthritis can sometimes be misleading. Seven of 69 patients with RA had radiographs sufficiently atypical to lead clinicians to suspect other disorders (e.g., gout, lupus erythematosis, thrombophlebitis). Five of these cases are presented and the diagnosis in each case is discussed.
