Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The left hilum is enlarged with a somewhat nodular contour . Given recent pulmonary infection with asthmatic symptoms , this could represent postinfectious adenopathy , however , with a history of multiple episodes of hemoptysis , a central bronchial mass can not be excluded and chest CT is recommended for further evaluation . The lungs are hyperinflated , suggesting small airways disease and air trapping , although this can be a normal finding in young patients with vigorous inspiratory effort . There is no focal consolidation , pleural effusion , pneumothorax , or pulmonary edema . The cardiac silhouette is within normal limits .
    OUTPUT:
    
1 . Enlarged left hilum for which a chest CT is recommended . 2 . Hyperinflation .
