    INPUT: Moderate right and small left pleural effusions are seen with overlying atelectasis . Medial right base opacity may be due to combination of pleural effusion and atelectasis , but underlying consolidation due to pneumonia is not excluded in the appropriate clinical setting . Subtle lateral left mid lung opacity projecting over the posterior left seventh rib is most likely due to overlap of structures ; previously seen left upper lung opacity is much less conspicuous on the current study .
    OUTPUT:
