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.
