    INPUT: Lung volumes have decreased in the interim . Left lower lobe opacity with air bronchogram stent silhouetting of the descending thoracic aorta and mild indistinctness of the medial left hemidiaphragm persists and is perhaps more conspicuous from the prior exam , consistent with left lower lobe pneumonia . Opacity in the right lower lobe is slightly more conspicuous , but in the setting of lower lung volumes , is consistent with atelectasis . No edema or pneumothorax . The cardiomediastinal silhouette is unchanged . The post pyloric enteric tube is only partially visualized .
    OUTPUT:
    
1 . Left lower lobe pneumonia . 2 . Lower lung volumes .
