Sternalis muscle also called rectus sternalis, rectus thoracis, or episternalis is an anomalous muscle of the anterior chest wall with unknown anatomical function. It is regularly observed in lower animal but infrequently in humans. Presence of this muscle can create confusion with tumours of the anterior chest wall during routine mammography. Although less is known about its origin and innervations, knowledge about this muscle can have many clinical implications. A case of unilateral sternalis muscle detected during mastectomy, in a female with carcinoma of the right breast, is being reported with a brief review of the literature and highlighting its clinical significance.
胸骨肌也被称为胸骨直肌、胸直肌或胸骨上肌，是前胸壁的一块异常肌肉，其解剖功能不明。在低等动物中常能观察到它，但在人类中较少见。在常规乳房X线摄影检查时，这块肌肉的存在可能会与前胸壁肿瘤相混淆。尽管对其起源和神经支配了解较少，但关于这块肌肉的知识可能具有许多临床意义。本文报告了一例在右乳腺癌女性患者乳房切除术中发现的单侧胸骨肌病例，并对相关文献进行简要回顾，强调其临床意义。
