We report a rare case of bilateral strap-like sternalis muscle of the anterior chest wall in a female cadaver. Its presence may evoke alterations in the electrocardiogram or confuse a routine mammography. The incidental finding of a sternalis muscle in mammography CT and MRI studies must be documented in a patient s medical records as it can be used as a pedicle flap or flap microvascular anastomosis during reconstructive surgery of the anterior chest wall head and neck and breast. Moreover its presence may be misdiagnosed as a wide range of benign and malignant anterior chest wall lesions and tumors. Background The sternalis muscle is an anatomical variant of the anterior thoracic region musculature well documented and familiar to anatomists but quite unknown among clinicians and radiologists 1 . It lies superficially and perpendicular to the pectoralis major muscle and parallel to the sternum. Many more terms have been used in the literature to describe sternalis muscle such as para-sternalis and rectus sterni muscle 2 3 . The muscle usually arises from the upper sternum and the infraclavicular region and can display variable insertion points such as the pectoral fascia lower ribs costal cartilages rectus abdominis muscle sheath or the abdominal external oblique muscle aponeurosis 4 5 . However there is a great variation in height cm width mm
