    INPUT: Compared to the scout view from the prior CT , the cardiac , mediastinal and hilar contours appear unchanged . There is a mild interstitial abnormality that is difficult to compare directly to the prior CT , but probably reflects edema and possibly superimposed airway inflammation or slight congestion . There are probably small bilateral pleural effusions . The lungs are hyperinflated . Exaggerated kyphotic curvature with mild - to - moderate loss in mid vertebral body heights appears similar . Regarding the left ribs , there are suspected nondisplaced fractures involving the left sixth and seventh ribs without displacement . There is no pneumothorax . The bones appear demineralized .
    OUTPUT:
    
Left - sided rib fractures . Mild interstitial abnormality , suggesting slight vascular congestion . Bony demineralization .
