    INPUT: The heart is normal in size . The mediastinal and hilar contours are unremarkable and appear not significantly changed allowing for differences in technique including low lung volumes . There are patchy opacifications in the lingula and even more extensive within the left lower lobe , where air bronchograms can also be seen , most suggestive of pneumonia . Elsewhere , the lungs appear clear . There are no pleural effusions or pneumothorax .
    OUTPUT:
    
New multifocal opacities in the left lung suggesting pneumonia . Followup radiographs are recommended following treatment within eight weeks in order to show resolution .
