Synovial cyst as differential diagnosis of supraclavicular mass in rheumatoid arthritis.
We describe a mass located at the supraclavicular space in a patient with a 5 year history of erosive rheumatoid arthritis. The mass was initially diagnosed as a suspected metastasis, but direct puncture and magnetic resonance imaging revealed a cyst. Clinical and radiological characteristics are described and pathogenesis and treatment are discussed.
