    INPUT: Again there is significant elevation of the left hemidiaphragm , increased as compared to the prior study . There are streaky opacities in the right infrahilar region , similar to slightly increased as compared to the prior study . The remainder of the lung fields are clear without focal opacity to suggest pneumonia . The cardiomediastinal silhouette is normal . The hilar contours are unremarkable . There is no pleural effusion or pneumothorax .
    OUTPUT:
    
1 . Severe elevation of the left hemidiaphragm , increased since the prior study . Direct visualization under fluoroscopy could help evaluate for diaphragmatic paralysis . 2 . Persistent streaky opacities in the right infrahilar region similar to slightly increased compared to the prior study may represent chronic atelectasis , underlying infection not entirely excluded . There is no other focal airspace opacity to suggest pneumonia .
