[Isolated bilateral Sternocostoclavicular Hyperostosis (SCCH) with a pathological clavicular fracture--a 10-year follow-up].

The presented case demonstrates the clinical and radiological course of a woman suffering from bilateral sternocostoclavicular hyperostosis (SCCH) from early changes to a spontaneous clavicula fracture after 10 years. SCCH is characterised by a chronic recurrent painful swelling of the sternoclavicular region due to an aseptic inflammation and hyperostosis of the clavicula, sternum, upper ribs and the adjacent soft tissues. Frequently the picture is accompanied by cutaneous and other skeletal symptoms. The disease can be part of the SAPHO (synovitis, acne, pustulosis, hyperostosis, osteitis) syndrome. The chronic process is represented by the typical "bull horn sign" in a bone scan. NSAIDS should represent the first line treatment.
