Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Compared 1 day prior , bilateral , predominantly perihilar interstitial opacities have increased , more likely pulmonary edema than bilateral pneumonia . Persistent small right apical pneumothorax . A small right pleural effusion has increased and a small left pleural effusion is unchanged . Right pleural drainage catheter is unchanged in position . Subcutaneous emphysema in the right lateral chest wall is similar . Mildly enlarged cardiomediastinal silhouette is unchanged in size . An air - fluid level projects over the expected location of the neo esophagus
    OUTPUT:
    
1 . Increasing pulmonary edema , alternatively worsening bilateral pneumonia . 2 . Persistent small right apical pneumothorax . 3 . Small right pleural effusion is increased and small left pleural effusion is unchanged . 4 . An air - fluid level is likely located within the neo esophagus . If there is legitimate clinical concern for a mediastinal collection , CT would be necessary for assessment .
