Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were obtained . The lungs are hyperinflated with flattening of the diaphragms . Slight blunting of the posterior costophrenic angles may relate to the hyperinflated lungs , although trace pleural effusions are not excluded . There is patchy opacity projecting over the left lower lung adjacent to the left heart border . Suggest oblique views for further evaluation . The mediastinum is not widened . The cardiac silhouette is not enlarged .
    OUTPUT:
    
1 . The mediastinum is not widened . 2 . Hyperinflated lungs . Slight blunting of the posterior costophrenic angles may relate to the hyperinflated lungs , although trace effusions not excluded . Opacity projecting just adjacent to the left heart border on the frontal view , not definitively seen on the lateral view may relate to nipple shadow or other external artifact . Suggest repeat with nipple markers and / or oblique views for confirmation .
