Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs are hyperinflated and diaphragms are flattened , consistent with COPD . There is mild to moderate cardiomegaly . Aorta is densely calcified and unfolded . Mitral annulus calcification is noted . There is upper zone redistribution , but no overt CHF . There is blunting of the costophrenic angles posteriorly with evidence for small right effusion and tiny left effusion . Minimal bibasilar atelectasis , but no frank consolidation . Ill - defined focal density at the right lung base laterally may represent artifact due to overlying rib shadows -- attention to this area on followup films is requested . Osteopenia and degenerative changes of the thoracic spine are noted .
    OUTPUT:
    
Hyperinflation suggestive of COPD . Mild to moderate cardiomegaly . Small right - greater - than - left pleural effusions . Minimal bibasilar atelectasis . No CHF or pneumonic infiltrate detected . Small ill - defined focal density at the right base laterally of uncertain etiology or significance -- attention on followup films is requested . Bilateral oblique AP views of the chest may help for further characterization .
