Rectus sternalis is a strap muscle occasionally present in anterior thoracic wall. Rectus sternalis if present, can be used in breast reconstruction surgeries after mastectomy in association with pectorals and also in head and neck reconstructive surgery. During routine dissection for the undergraduates on the anterior thoracic wall, unilateral presence of rectus sternalis muscle was found on right side of the chest. The muscle was extending from 5th rib on the right side (3.6 cm away from sternum) to sternum (at the level of manubriosternal junction). The muscle was 7.2 cm long and 0.8 cm broad in the middle part of the muscle. Both attachments were tendinous. This strap like muscle was seen running between superficial fascia and pectoral fascia of the chest. It may cause confusion as tumor mass or desmoids in anterior chest wall. In this case, rectus sternalis was seen associated with renovascular and other musculoskeletal anomalies. Accidental finding of rectus sternalis might be a predictor for renovascular anomaly for surgeons and radiologist.
