Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lung volumes are low which causes accentuation of the cardiomediastinal silhouette which is at least borderline enlarged . There is again crowding of the bronchovascular structures without definite evidence of pulmonary edema . Assessment of the lung bases is limited due to presence of low lung volumes but there is at least bibasilar atelectasis . A band - like linear density overlying the right lower lung is likely secondary to atelectasis . There is no evidence of pneumothorax . Osseous fragmentation of the distal right clavicle is compatible with remote trauma .
    OUTPUT:
    
Bibasilar consolidations as well as low lung volumes resulting in crowding of the bronchovascular structures ; most likely due to atelectasis , however pneumonia can be considered in the appropriate clinical setting .
