Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Cardiomediastinal contours are stable in appearance . A dominant 2 .8 cm diameter nodule in the right lower lobe has increased in size since the prior CT torso . A centrally located left suprahilar nodule is difficult to compare to the prior study but may also be slightly larger . Hazy opacity adjacent to the right heart border , probably relates to a known chest wall mass seen on prior CT . Linear areas of scar or atelectasis are present within the left lower and right middle lobes , but there are no new areas of consolidation to suggest the presence of pneumonia . A small portion of the periphery of the right base was excluded from the current exam .
    OUTPUT:
    
No definite pneumonia . If clinical suspicion persists , consider repeat chest radiograph with improved inspiratory level to allow more complete assessment of the lung bases .
