Isolated traumatic pectoralis minor tendon tear in a young adult diagnosed with MRI

This is a rare case of an isolated pectoralis minor partial-thickness tendon tear in a 24-year-old man who was involved in a major trauma. The purpose of this paper is to report the clinical signs, symptoms, cross-sectional imaging findings, and management of an isolated pectoralis minor tendon tear. Furthermore, this case represents a novel traumatic mechanism of injury, as opposed to the classic sports-related pectoralis minor tendon tear injury. The current limited body of literature on isolated pectoralis minor tendon tears is reviewed.
