Seat belt injuries of the breast

The purpose of this study was to determine the mammographic and sonographic findings of injuries of the breast caused by seat belts in automobile accidents. The study concluded that Mammograms in women with breast injuries caused by seat belts show areas of contusion, lipid cysts, and parenchymal calcifications occurring in a bandlike distribution corresponding to the path of the seat belt shoulder restraint across the chest. Lipid cysts are seen sonographically as smoothly marginated anechoic or hypoechoic nodules.
