    INPUT: The heart is normal in size . The mediastinal and hilar contours appear within normal limits . There are new streaky left basilar opacities , probably within the lingula , although not well seen on the lateral view . These are most suggestive of minor atelectasis but are not entirely specific . Elsewhere , the lungs appear clear . There are no pleural effusions or pneumothorax . Mild rightward convex mid thoracic spinal curvature is similar . Otherwise , bony structures are unremarkable .
    OUTPUT:
    
Streaky left basilar opacities , not entirely specific but most suggestive of minor atelectasis . In the appropriate clinical setting , however , mild or early bronchopneumonia is not excluded .
