The palmaris longus frequently exhibits anatomical variations with palmaris longus agenesis and reversal being the most prevalent. These variations are relevant clinically, as the muscle is often used during plastic surgeries for grafting tendons. They are also relevant in pathology, as hypertrophy of the reversed muscle is related to median nerve compression. In this report, we describe an unusual case in which a male cadaver-donor exhibited a right-sided palmaris longus reversal and left-sided palmaris longus agenesis. Review of the literature documents no previous co-occurrence of these anomalies. Since the muscle has relevance in a variety of contexts within medicine and surgery, reporting on a variation like this carries significant educational and clinical value.
掌长肌经常出现解剖变异，其中掌长肌缺如和掌长肌反转最为常见。这些变异在临床上具有相关性，因为在整形外科手术中肌腱移植时常会用到该肌肉。它们在病理学上也具有相关性，因为反转肌肉的肥大与正中神经受压有关。在本报告中，我们描述了一个不寻常的案例，一名男性尸体供体表现为右侧掌长肌反转和左侧掌长肌缺如。文献回顾表明此前没有这些异常同时出现的记录。由于该肌肉在医学和外科的多种情况下都具有相关性，报告这样的变异具有重要的教育和临床价值。
