Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is normal in size . The mediastinal and hilar contours appear within normal limits . There is no pleural effusion or pneumothorax . There is a vague opacity in the lateral aspect of the right upper lobe immediately above the minor fissure with bronchial cuffing . A similar finding is noted in the left upper lung but the latter may refer to the lingula since the lateral is suggestive of vague anterior opacity at that location . Bony structures are unremarkable .
    OUTPUT:
    
Vague areas of increased interstitial prominence with peribronchial cuffing which may represent an early infectious process , perhaps referring primarily to airways , but including a relatively focal anterior opacity perhaps referring to the lingula . Entities such as pneumocystis may be fairly occult in this context on radiography . Follow - up radiographs are suggested .
