Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Again seen is a small right apical pneumothorax , probably very slightly smaller compared with the prior film . Atelectasis and minimal pleural fluid at the left base are also again seen . The degree of atelectasis may be very slightly worse . Otherwise , I doubt significant interval change . Again seen is the chest tube at the right lung base , with right base atelectasis medially , but no gross right pleural effusion . No left - sided pneumothorax is detected .
    OUTPUT:
    
1 . Right apical pneumothorax remains present , very slightly smaller than on the prior film . 2 . Left base atelectasis may be slightly worse . 3 . Otherwise , I doubt significant change .
