    INPUT: Lung volumes remain low resulting in bronchovascular crowding . There is central pulmonary vascular congestion though no overt interstitial edema . No large pleural effusion is evident . There is no confluent consolidation or pneumothorax . Cardiomediastinal and hilar contours are within normal limits . Air fluid levels identified in the upper abdomen .
    OUTPUT:
    
Low lung volumes with possible central pulmonary vascular congestion without overt interstitial edema . No consolidation to suggest pneumonia . Multiple air fluid levels in upper abdomen better characterized by subsequent abdominal CT .
