Bilateral Psoas Minor: A Case Report with Clinical, Embryological, and Evolutionary Insights

Abstract

A 57-year-old female cadaver donated for research contained an accidental bilateral presence of the psoas minor (PMn) muscle. Bilateral PMn is a rare finding but it may be associated with other anatomical variations or abnormalities in the abdomen or pelvis. In some cases, the muscle may be involved in the development of certain medical conditions or may compress nearby structures, leading to symptoms such as pain or discomfort. Overall, bilateral PMn is a relatively uncommon anatomical variation that may be of interest to anatomists or medical professionals. A thorough understanding of this muscle is essential, particularly when making a clinical diagnosis and carrying out procedures in the iliac area. In this case report, we tried to discuss the clinical, embryological, and evolutionary significance of PMn muscle.
