Sternocostoclavicular hyperostosis is a rare but recognized entity characterized by new bone formation and ligamentous ossification which limits mobility of the sternoclavicular joints. Aetiology is obscure and debated. There may be considerable delay in establishing the diagnosis, even by specialists. In confirming the diagnosis plain radiography is of limited value but radionuclide bone scan and computed tomography (CT) may be helpful. Four cases are described to emphasize these points and illustrate the clinical and radiological features of the condition. High resolution CT with thin sections (5 mm or less) is the examination of choice for demonstrating the characteristic features and is essential if the condition is to be confirmed in its early stages when treatment might be more successful in delaying progression.
胸锁关节骨肥厚是一种罕见但已被认可的疾病，其特征为新骨形成和韧带骨化，这会限制胸锁关节的活动度。病因尚不明确且存在争议。即使是专科医生，在确诊方面也可能会有相当长的延迟。在确诊时，普通X线摄影的价值有限，但放射性核素骨扫描和计算机断层扫描（CT）可能会有所帮助。本文描述了4例病例，以强调这些要点，并说明该疾病的临床和放射学特征。采用薄层（5毫米或更薄）的高分辨率CT是显示特征性表现的首选检查方法，而且如果要在疾病早期确诊，这是必不可少的，因为早期治疗在延缓病情进展方面可能会更成功。
