Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is at the upper limits of normal size . The mediastinal and hilar contours appear within normal limits . There are streaky basilar opacities most suggestive of atelectasis . These are somewhat conspicuous in the retrocardiac area on the lateral view . There is a slight peribronchial vascular thickening bilaterally with peribronchial cuffing suggesting an inflammatory or perhaps infectious process involving lower airways . Moderate degenerative changes are noted along the lower thoracic spine .
    OUTPUT:
    
Mildly prominent interstitium with peribronchial cuffing for which differential considerations include inflammation or potentially infection involving lower airways . Although bronchopneumonia is difficult to entirely exclude , streaky basilar opacities are probably due to the same process and atelectasis rather than consolidative pneumonia .
