Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is at the upper limits of normal size . The mediastinal and hilar contours appear within normal limits . There is no pleural effusion or pneumothorax . There is a vague opacity projecting over the right lower lung and breast , potentially a nipple shadow ; alternatively perhaps it may reflect a confluence of bronchovascular opacities or atelectasis . Elsewhere , the lungs appear clear . The lungs are hyperinflated . Small osteophytes are noted along the mid thoracic spine .
    OUTPUT:
    
Hyperinflation . No evidence of acute disease . Vague nodular opacity projecting over the right lower lung field , possibly a nipple shadow . When clinically appropriate , a repeat PA view with nipple markers is recommended to assess further .
