    INPUT: Low lung volumes cause bronchovascular crowding and bilateral atelectasis . Allowing for this there is likely mild central pulmonary vascular congestion , similar to the prior study without overt pulmonary edema . There is no pleural effusion or pneumothorax . The cardiomediastinal silhouette is within normal limits . A right PICC terminates in the low SVC . A 3 mm right lower lung nodule corresponds to a granuloma seen on recent chest CT .
    OUTPUT:
    
Unchanged mild central pulmonary vascular congestion without frank pulmonary edema .
