Variations of the pectoralis major muscle are commonly seen. However, during the routine dissection of an adult male cadaver, an apparently uncommon muscular variant was identified. In this cadaver, the sternal heads of the left and right pectoralis muscles crossed the midline and interdigitated with one another. In addition, the clavicular heads of both pectoralis major muscles were separated from the remaining parts of the muscles. Such anatomical variants such be kept in mind by clinicians and surgeons during patient evaluation and treatment.
胸大肌变异较为常见。然而，在一具成年男性尸体的常规解剖过程中，发现了一种明显不常见的肌肉变异。在这具尸体中，左右胸大肌的胸骨头越过中线并相互交错。此外，两侧胸大肌的锁骨头与肌肉的其余部分分离。临床医生和外科医生在对患者进行评估和治疗时应牢记这种解剖变异。
