    INPUT: The heart is normal in size . The mediastinal and hilar contours appear unchanged . There is no evidence for pneumothorax , pneumomediastinum , or pleural effusion . Streaky basilar opacities are more conspicuous in the right lower lung ( probably within the right lower lobe ) compared to the lingular region ; these are non-specific . Bony structures are unremarkable .
    OUTPUT:
    
No evidence for pneumomediastinum or esophageal thickening . Patchy lower lung opacities , nonspecific and probably compatible with atelectasis . In the appropriate clinical setting , however , aspiration or pneumonia could be given consideration .
