Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Compared to previous exam , there has been no significant interval change . Again seen is volume loss in the right hemithorax with increased density in the right paratracheal region . Some of this is likely due to post-radiation changes . There is no visualized pneumothorax on the current exam . Right basilar Pleurx catheter remains in place with some fluid within the major fissure , unchanged . The left lung remains grossly clear . Cardiomediastinal silhouette is stable . Stents again identified in the descending thoracic and upper abdominal aorta . No acute osseous abnormalities .
    OUTPUT:
    
No definite acute cardiopulmonary process . Presumably in part post - treatment changes with volume loss in the right Pleurx catheter and right paramediastinal soft tissue density .
