Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An apparent slight increase in the right basal pleural effusion is likely due to dependent a layering . An endotracheal tube is in - situ , the tip terminates approximately 5 .5 cm above the level of the carina . A nasoenteric tube is in - situ , the tip is not visualized but lies below the left hemidiaphragm . There is persistent bibasilar atelectasis . Prominence of the bilateral hila and moderate cardiomegaly suggests a degree of congestive heart failure but no frank pulmonary edema . No pneumothorax seen . Apparent widening of the superior mediastinum is similar when compared to prior studies and likely related to the AP supine technique .
    OUTPUT:
    
Apparent increase in the right pleural effusion likely due to dependent layering . Otherwise , no significant interval change .
