Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single semi-erect AP portable view of the chest was obtained . There is interval placement of a right internal jugular central venous catheter terminating in the low SVC without findings to suggest pneumothorax . Left base retrocardiac opacity appears increased , consistent with known left lower lobe collapse seen on preceding CT with small right pleural effusion . Right basilar atelectasis / consolidation seen on preceding CT is not well appreciated on the current study . There is no large right pleural effusion . The cardiac and mediastinal silhouettes are stable .
    OUTPUT:
    
Interval placement of right internal jugular central venous catheter terminating in the low SVC without evidence of pneumothorax . Interval increase in left basilar / retrocardiac opacity which may be due to atelectasis / left lower lobe collapse .
