    INPUT: A new left - sided chest tube is noted projecting over the lung base . There has been significant evacuation of the left - sided pleural effusion with some residual effusion still noted . A small apical pneumothorax is present . Patchy opacities in the left upper / mid lung can not be compared with prior exam as these were obscured by the layering effusion but may represent atelectasis . The right lung is clear . There is no right - sided pleural effusion or pneumothorax . Cardiac size can not be assessed due to obscuration of the left heart border .
    OUTPUT:
    
1 . New left - sided chest tube in appropriate position . Significant interval improvement of left - sided pleural effusion post-evacuation . Small apical left - sided pneumothorax is present . 2 . Hazy patchy opacities in the left upper / mid lung may represent atelectasis . Attention on follow up is recommended .
