Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size and mediastinal contours are normal . A diffuse linear pattern in the mid and lower lungs is new from the prior radiograph and is accompanied by peribronchial cuffing and patchy peribronchiolar opacities particularly in the right infrahilar region . Hyperlucency of upper lobes with associated attenuation of the vasculature is in keeping with upper - lobe - predominant emphysema . There are no pleural effusions or acute skeletal findings .
    OUTPUT:
    
Bronchial wall thickening and diffuse interstitial opacities probably represent an atypical pneumonia in the setting of fever . An atypical distribution of pulmonary edema in the setting of upper lobe predominant emphysema is an additional consideration .
