IMPRESSION:
Compared to previous radiograph of 1 day earlier, moderate right and small
 left pleural effusions are a persistent finding as well as large calcified
 pleural plaques in the left mid and lower hemi thorax.  There remains a
 suggestion of a possible small lateral left pneumothorax, which could be
 confirmed or excluded by additional right lateral decubitus view of the left
 lung if warranted clinically.
