    INPUT: The lungs are well expanded with increased interstitial markings which likely reflect chronic changes due to a nonspecific fibrotic lung disease as on the prior CT . Increased bibasilar opacities may reflect superimposed atelectasis ; however aspiration would be difficult to exclude . There is no pleural effusion or pneumothorax . The heart is normal in size with normal mediastinal and hilar contours aside from enlarged pulmonary arteries consistent with provided history of pulmonary hypertension . Proximal left clavicular fracture is redemonstrated .
    OUTPUT:
    
Chronic fibrotic changes with superimposed increased basilar opacities which could reflect atelectasis or aspiration .
