Jaccoud's arthropathy in systemic lupus erythematosus: Differentiation of deforming and erosive patterns by magnetic resonance imaging

Abstract

In SLE patients with arthritis of the finger joints, MRI detects characteristic signs of soft tissue pathology (e.g., capsular swelling, edematous and proliferative tenosynovitis, synovial hypertrophy) and bony alterations (e.g., erosions, some of which are missed by conventional radiography). MRI thus helps to distinguish different types of lupus arthritis/Jaccoud's arthropathy, which allows more differentiated treatment strategies and monitoring.
