Imaging differential diagnosis for rheumatoid arthritis Imaging differential diagnosis for rheumatoid arthritis. (A) Chronic calcium pyrophosphate crystal inflammatory arthritis with radiocarpal, intercarpal, metacarpophalangeal, and interphalangeal joint space narrowing. Changes of osteoarthritis are seen at the distal interphalangeal joints and at the carpometacarpal and interphalangeal joints of the thumb. Chondrocalcinosis is present at the triangular fibrocartilage complex (white arrowhead). A hooklike osteophyte is seen at the index finger metacarpal head (white arrow). No erosion is seen. (B) Chronic calcium pyrophosphate crystal inflammatory arthritis in another patient showing chondrocalcinosis at the wrist (white arrowheads) and widening of the scapholunate interval. (C) Psoriatic arthritis with erosion at the thumb metacarpal head (black arrowhead) as well as several areas of proliferative bone formation (black arrows). (Case used with permission from Dr Hansel Otero, Tufts Medical Center, Boston, MA.) (D) Juvenile idiopathic arthritis with advanced destruction of multiple joints, ankylosis (joint fusion) at the wrist, and overgrowth of the metacarpal heads.
