    INPUT: Frontal and lateral views of the chest were obtained . There are low lung volumes . Left lower lobe opacity and to a lesser extent lingular opacity seen , which could be due to atelectasis , although findings are concerning for consolidation due to pneumonia . No large pleural effusion is seen , although a trace left pleural effusion is difficult to exclude . No evidence of pneumothorax is seen . The cardiac silhouette is top normal , likely accentuated by low lung volumes .
    OUTPUT:
    
Low lung volumes . Left lower lobe and to a lesser extent lingular opacities raise concern for underlying pneumonia with possibly associated atelectasis . No right pleural effusion . Difficult to exclude trace left pleural effusion .
