The usual appearance of the postoperative chest radiograph in patients after coronary artery bypass surgery is well known. The article describes an unusual case with development of a right anterior mediastinal mass after bypass surgery with internal mammary artery grafts. This mediastinal mass, initially detected on a chest radiograph, was confirmed by contrast-enhanced chest CT to be intrathoracic fat from the right internal mammary artery pedicle.
