Juvenile idiopathic arthritis (JIA) is an inflammatory disorder of connective tissue. Joint pain or tenderness, and swelling affecting one or more joints for at least six weeks, in patients under the age of 16 years, are diagnostic of JIA. Involvement of the juxta-articular structures is less common in JIA compared to adult rheumatoid
arthritis. We present a case of JIA with bilateral sternoclavicular synovial cysts.
