The heart size is unchanged . A right pleural catheter is in standard placement . An air - fluid level projects over the right mainstem bronchus , likely representing the neo-esophagus . Substantial subcutaneous emphysema is mildly increased in prominence compared to prior exam .
    OUTPUT:
    
1 . Interval improvement in previously noted mild pulmonary edema since ___ . 2 . Persistent small right apical pneumothorax . 3 . Unchanged bilateral small pleural effusions and bibasilar atelectasis since ___ . 4 . An air - fluid level projects over the right mainstem bronchus , likely representing the neo esophagus .
