Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart appears mildly enlarged . The mediastinal and hilar contours are essentially unchanged allowing for differences in technique . One change is that the central pulmonary arteries appears somewhat larger and the lungs are hyperinflated suggesting there may be obstructive lung disease . There is suspected hiatal hernia , moderate in size and located somewhat to the left line , but similar to the remote prior study . Streaky left basilar opacities suggest associated atelectasis or scarring . There is no definite pleural effusion or pneumothorax . Bony structures are unremarkable . Mild rightward convex curvature is centered along the mid thoracic spine .
    OUTPUT:
    
Findings which may suggest obstructive pulmonary disease with streaky left basilar opacification , most suggestive of atelectasis , in association with a suspected hiatal hernia .
