Musculoskeletal (MS) involvement is the most common group of symptoms in patients with SLE (70%-95% over the disease course and up to 60% during disease flares), or even as a first presenting symptom in up to 50% of cases (3-5).Therefore, the clinical picture varies from transient or
migratory arthralgia, non-deforming and nonerosive arthritis, and tenosynovitis to Jaccoud's arthropathy, which shows deformities with none or few bone erosions, depending on the imaging technigue used (3, 4).
