Cleft sternum is an extremely rare anomaly of development. It results from failure of fusion of midline structures that contribute to the formation of the sternum. The defect may affect the upper sternum, the lower sternum, or the whole sternum. Most cases are diagnosed in childhood when it is associated with serious midline defects. We present a case of an isolated upper sternal cleft in a 55-year-old adult, found accidentally on bone scan. To our knowledge, no bone scan image of cleft sternum could be found in the literature.
胸骨裂是一种极为罕见的发育异常。它是由于中线结构融合失败导致胸骨形成缺陷所致。该缺陷可能影响胸骨上部、下部或整个胸骨。大多数病例在儿童期诊断，此时常伴有严重的中线缺陷。我们报告一例 55 岁成年患者的孤立性胸骨上部裂，该患者在骨扫描时偶然发现。据我们所知，文献中未报道过胸骨裂的骨扫描图像。
