    INPUT: The cardiac , mediastinal and hilar contours appear unchanged . The heart is again borderline in size and again with a left ventricular configuration . There is patchy increased density and bronchial cuffing in each mid lung , suggesting airway inflammation , probably chronic . A trace pleural effusion is suspected on the right only . The bones are probably demineralized to some extent . There is no pneumothorax . An irregular contour to the sternum suggests a fracture , including a small displaced step - off appearance , new since the remote prior studies . There is no soft tissue density effacing the anterior clear space deep to the sternum .
    OUTPUT:
    
1 . Findings suggesting a mildly displaced sternal fracture , new since ___ years ago , although otherwise age - indeterminant . No surrounding soft tissue reaction . Correlation with physical findings is recommended . 2 . No evidence of acute cardiopulmonary disease .
