Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac , mediastinal and hilar contours appear unchanged . The heart is at the upper limits of normal size . There is no pleural effusion or pneumothorax . Central streaky opacities suggesting airway inflammation , including peribronchial cuffing . Although other etiologies including mild fluid overload are differential considerations , inflammatory change seems more likely . However , there is also the possibility of a developing perihilar opacity in the right lower lobe since opacities are somewhat confluent there .
    OUTPUT:
    
Findings suggesting bronchial inflammation with potential for developing opacity in the right lower lobe which may indicate early development of pneumonia .
