    INPUT: The heart is normal in size . The mediastinal and hilar contours appear within normal limits . There are no pleural effusions or pneumothorax . There is a vague nodular opacity projecting over the right upper lung , suggesting a small focus of pneumonia in the appropriate clinical setting . Elsewhere , the lungs appear clear . The osseous structures are unremarkable .
    OUTPUT:
    
Vague somewhat nodular opacity , quite small and measuring about 1 cm in the right upper lung . Noting demographics , morphology and patient presentation , this appearance is suspected to represent pneumonia , but followup radiographs are recommended in eight weeks in order to assure resolution .
