Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is borderline in size . The mediastinal and hilar contours appear within normal limits . A patchy left lower lung opacity is probably in the left lower lobe . On the right , more extensive opacification along the right mid lung is probably posterior , but not well seen on the lateral view , although most likely referring primarily to the superior segment of the left lower lobe . The chest is hyperinflated . There is no definite pleural effusion or pneumothorax . Bony structures appear within normal limits .
    OUTPUT:
    
Multifocal opacities suggesting pneumonia , although opacities appear probably for the most part in dependent areas , and in the setting of altered mental status , aspiration pneumonitis is an additional consideration .
