Abstract
During a routine dissection of a 99-year-old female cadaver we encountered the presence of bilateral supernumerary muscles in the pectoral region. The muscle originated on the anterior surface of the fourth rib and inserted onto the coracoid process and anterior glenohumeral joint capsule via an aponeurosis and was deduced to be the pectoralis intermedius muscle. The pectoralis minor muscle was found to have originated on ribs 2 to 4 anteriorly and inserted into the coracoid process of the scapuvdla thereby shifting cranially. The pectoralis intermedius muscle has controversial classifications and variable embryological origin theories, thus making it not only a rare muscle to encounter but a difficult one to categorize. The objective of this investigation was to study a rare case of bilateral pectoralis intermedius muscle aberrations and discuss its clinical significance.
期刊介绍：
Translational Research in Anatomy is an international peer-reviewed and open access journal that publishes high-quality original papers. Focusing on translational research, the journal aims to disseminate the knowledge that is gained in the basic science of anatomy and to apply it to the diagnosis and treatment of human pathology in order to improve individual patient well-being. Topics published in Translational Research in Anatomy include anatomy in all of its aspects, especially those that have application to other scientific disciplines including the health sciences: • gross anatomy • neuroanatomy • histology • immunohistochemistry • comparative anatomy • embryology • molecular biology • microscopic anatomy • forensics • imaging/radiology • medical education Priority will be given to studies that clearly articulate their relevance to the broader aspects of anatomy and how they can impact patient care.Strengthening the ties between morphological research and medicine will foster collaboration between anatomists and physicians. Therefore, Translational Research in Anatomy will serve as a platform for communication and understanding between the disciplines of anatomy and medicine and will aid in the dissemination of anatomical research. The journal accepts the following article types: 1. Review articles 2. Original research papers 3. New state-of-the-art methods of research in the field of anatomy including imaging, dissection methods, medical devices and quantitation 4. Education papers (teaching technologies/methods in medical education in anatomy) 5. Commentaries 6. Letters to the Editor 7. Selected conference papers 8. Case Reports
