    INPUT: A left - sided pacemaker remains in place . A right upper lobe consolidation with a component of volume loss is unchanged . Small bilateral pleural effusions are unchanged , left greater than right . An airspace opacity at the left lung base may be due to infection and / or atelectasis . There is no pneumothorax . The cardiomediastinal silhouette is stable . Right costophrenic angle opacification could be due to vessels or atelectasis , but the possibility of superimposed pneumonia would have to be considered in the appropriate clinical setting .
    OUTPUT:
    
Unchanged right upper lobe consolidation which is most compatible with pneumonia . Stable retrocardiac airspace opacity which may be due to atelectasis or infection . Stable small bilateral pleural effusions , left greater than right .
