title: Unilateral sternocostoclavicular hyperostosis in a patient with ankylosing spondylitis: A case report with color Doppler ultrasonogram findings.
abstract: Sternocostoclavicular hyperostosis is a chronic inflammatory disorder affecting the sternoclavicular joint and upper ribs. There is a strong association with seronegative spondyloarthropathy in which bilateral involvement is common. Ultrasonography and Color Doppler findings of this entity have not been described previously, to the best of our knowledge. We describe the findings in a patient of ankylosing spondylitis who was referred for unilateral sternoclavicular joint swelling.
