BACKGROUND: Numerous anatomical variations have been documented in muscles from various human body regions. Here, we describe an exceptionally uncommon instance of a psoas major muscle exhibiting a multiheaded configuration with diverse morphology. MATERIALS AND METHODS: During a routine dissection of the posterior abdominal wall, an abnormal muscle was observed. The muscle was identified, photographed, and subjected to further measurement. CONCLUSIONS: Atypical morphology of commonly occurring anatomical structures may lead to numerous clinical consequences, therefore knowledge regarding morphological variability seems crucial and worth documenting.
