    INPUT: Exam limited by motion . Lower lung volumes seen on the current exam with secondary crowding of the bronchovascular markings and probable superimposed vascular congestion . There is more confluent opacity in the left mid lung . There is no large effusion . The cardiac silhouette is enlarged but stable . Anterior cervical fixation hardware is visualized . There is asymmetric opacity in the left mid lung
    OUTPUT:
    
Low lung volumes with probable vascular congestion . More focal opacity in the left mid lung could represent superimposed pneumonia . Consider PA and lateral if patient is amenable .
