Exploring anomalous muscular architecture: a case of the dorsoepitrochlearis muscle

Anatomic variations in the upper limb are of great significance as they pose implications on surgical techniques and raise the risk of intraoperative injury.The presence of dorsoepitrochlearis muscle was discovered during routine dissection of a male cadaver at the Department of Human Anatomy. This variant muscle was found in the right axillary region, originating as a single strip from latissimus dorsi and attaching onto the medial epicondyle of the humerus. Dorsoepitrochlearis is a rare anatomical variation whose spectrum of clinical manifestation may extend from asymptomatic to muscular paresthesia and atrophy as well as motion restriction. A rich basis of knowledge of anatomical variations is crucial in diagnosis and management.
