Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A small opacity within the right lung apex is unchanged . This could reflect an area of confluent consolidation , though also could be residual scarring at that site . Lung volumes are low resulting in bronchovascular crowding with mild pulmonary vascular congestion . However , no other confluent consolidations are identified . No large pleural effusions are identified . Cardiomediastinal and hilar contours are within normal limits . Surgical clips are seen within the right upper quadrant .
    OUTPUT:
    
1 . Small focal opacity in the right lung apex , similar to prior . Findings could reflect focal pneumonia , though could also be related to scarring at the site of prior infection . 2 . Mild pulmonary vascular congestion .
