Sternocostoclavicular hyperostosis (SCCH) is a chronic, nonsuppurative inflammatory disease involving sternum, clavicle, upper ribs and its adjacent soft tissue. It is a relatively newly described syndrome, characterized by ossification in the region between the clavicle and the first rib, and hyperostosis of the medial end of the clavicle with simultaneous involvement of the sternum and juxtasterna1 ribs. We experienced one case of sternocostoclavicular hyperostosis, diagnosed by pinhole bone scintigraphy. This paper describes characteristic pinhole scintigraphic findings of SCCH, with comparative study with radiographic and pathologic findings.
