Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is borderline enlarged . The mediastinal and hilar contours appear unremarkable aside from mild unfolding of the descending thoracic aorta . The chest is hyperinflated . There is potentially a very small pleural effusion on the right and it is difficult to exclude one on the left . Although an infection is difficult to completely exclude , streaky opacities in the lower lungs are more suggestive of scarring than anything else by morphology . Bony structures are unremarkable .
    OUTPUT:
    
Multifocal basilar opacities , although more suggestive of scarring than pneumonia . Correlation with radiographs may be helpful if available , and if pneumonia is a persistent clinical concern , follow - up radiographs could be considered . Suspected trace pleural effusion on the right . Hyperinflation .
