Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size , mediastinal and hilar contours are within normal limits . Multifocal opacities within the right lung show interval improvement , particularly peribronchovascular opacities in the right upper lobe . Consolidation within the right lower lobe has also improved , particularly as viewed on the lateral projection . Small right pleural effusion has slightly decreased in size . Left lung and pleural surfaces are clear except for a very subtle area of opacity in the periphery of the left upper lobe , which has decreased since the prior radiograph as well .
    OUTPUT:
    
Rapidly improving predominantly right - sided lung opacities , which may be due to provided history of alveolar hemorrhage . Pulmonary infection could have a similar radiographic appearance . Continued followup is recommended to document complete resolution .
