Researchers at the University of California, Irvine, reviewed 23 contrast-enhanced MRI studies of patients with psoriatic arthritis (PsA). MRIs of patients’ hands and wrists were evaluated for the presence of erosions, bone marrow edema, joint synovitis, tenosynovitis, carpal tunnel, and soft tissue involvement. MRI images showed a presence of tenosynovitis (100% of wrists and hands), median nerve enhancement (80% of wrists), bone erosions (80% of wrists), triangular fibrocartilage tears (60% of wrists), wrist soft tissue involvement (90% of wrists), and wrists and hand joint synovitis (100% of wrists and hands). Researchers found that the rheumatoid-like distribution of bony lesions was common among the study participants. Based on their findings, researchers suggest that bone marrow edema, erosions, tendon and soft tissue disease, and median nerve involvement are present in patients with PsA. They also found that PsA affects patients’ wrists more than their hands.
