Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is a diffuse interstitial abnormality that is likely chronic in nature , not significantly changed compared to the prior chest radiograph from ___ . Increased left retrocardiac consolidation is at least partially attributable to worsening atelectasis , although infection at the left base is certainly possible . Heterogeneous right lower lung opacities have also increased , possibly secondary to increased atelectasis or new aspiration pneumonitis / pneumonia . Small bilateral pleural effusions are possibly increased , not well assessed on the single portable radiograph from ___ . The heart size is normal . The mediastinal contours are normal . There is no pneumothorax . Multilevel degenerative changes of the thoracolumbar spine are noted .
    OUTPUT:
    
1 . Increased left retrocardiac consolidation , likely at least partially attributable to increased atelectasis , although infection or aspiration pneumonitis in this region is certainly possible . 2 . Increased right lower lung heterogeneous opacities , likely secondary to a combination of atelectasis and aspiration pneumonitis / pneumonia . 3 . Small bilateral pleural effusions , possibly slightly increased in size compared to the prior study from ___ . Findings were discussed with Dr . ___ by Dr . ___ at 4 :03 p .m . via telephone on the day of the study .
