    INPUT: The cardiac , mediastinal , and hilar contours appear unchanged . There is persistent opacification of the left lower hemithorax with a suspected moderate pleural effusion . Persistent multifocal opacities in the right lung as well as a small band - like left mid lung opacity suggest multifocal atelectasis . There is a small area of vague lucency near the prior entry site of the right - sided chest tube which suggests there may be a trace loculated pneumothorax in the area as well as minimal subcutaneous emphysema . However , the lung is expanded and there are no other areas of suspected intrathoracic air . ___ project along the base of the left neck .
    OUTPUT:
    
1 . Persistent left basilar opacification suggesting pleural effusion with associated atelectasis . Infection is difficult to exclude , however . 2 . Small area of lucency along the course of the prior chest tube near its entry site into the right lower lateral chest , suggesting a very small loculated pneumothorax .
