Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A tracheostomy tube is appropriately positioned . An enteric catheter is visualized only to the level of the thoracic inlet , likely obscured more distally due to underpenetration of this radiograph . A metallic stent within the right main stem bronchus appears appropriately positioned . A left internal jugular central venous catheter ends at the confluence of the brachiocephalic veins , not significantly changed . A right superior mediastinal mass extends to the right hilus , not significantly changed . Fluid within the minor fissure is increased . There is mild - to - moderate bibasilar atelectasis . Small layering pleural effusions may be present , not significantly changed . There is no pneumothorax . Mild cardiomegaly is not significantly changed .
    OUTPUT:
    
1 . Unchanged moderate bibasilar atelectasis . 2 . Possible small bilateral pleural effusions , not significantly changed . 3 . Mild cardiomegaly , not significantly changed . 4 . Incompletely assessed enteric catheter , only visualized to the level of the thoracic inlet . Recommend conventional PA and lateral radiographs on future studies to improve visualization .
