    INPUT: Lung volumes are low . The heart size is mildly enlarged . The aorta is tortuous . There is mild pulmonary vascular congestion . Streaky bibasilar airspace opacities may reflect atelectasis though infection or aspiration can not be completely excluded . Blunting of the costophrenic angles on the lateral view suggests small bilateral pleural effusions . Elevation of the right hemidiaphragm is unchanged . No pneumothorax is present . Multiple old left - sided rib fractures are present .
    OUTPUT:
    
Mild pulmonary vascular congestion and small bilateral pleural effusions . Streaky bibasilar airspace opacities , possibly atelectasis but infection or aspiration can not be excluded .
