Stable patchy air space opacities in the upper lung fields bilaterally, with the right base relatively spared. The dense retrocardiac opacity is unchanged, suggesting focal infection, compressive atelectasis, consolidation, or aspiration. No new focal opacities or radiographic changes are identified.
