The sternalis muscle is a normal anatomic variant, which exists in about 5 to 8% of people. It runs longitudinally superficial to pectoralis major, alongside the sternum. Although the sternalis seems common in cadaveric studies, physicians are not familiar with it, which may lead to confusion in diagnosis. Occasionally, the sternalis may be misinterpreted as a breast mass on mammogramm. In that case, computed tomography and magnetic resonance imaging are useful. We report herein two cases of sternalis muscles encountered during mastectomy.
胸骨肌是一种正常的解剖变异，约5%至8%的人存在该肌肉。它纵向走行于胸大肌表面，沿胸骨两侧分布。尽管在尸体研究中胸骨肌似乎较为常见，但医生对其并不熟悉，这可能导致诊断混淆。偶尔，在乳房X线摄影中胸骨肌可能被误诊为乳腺肿块。在这种情况下，计算机断层扫描和磁共振成像很有用。我们在此报告两例在乳房切除术中遇到胸骨肌的病例。
