Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The right - sided catheter is again seen , similar in position . There is been progressive re-expansion of the right lung , with decrease in size of the right apical pneumothorax and of the pneumothorax seen at the right lung base . There is residual atelectasis at the right lung base , but this is also improved . There does appear to be a small right effusion , similar prior , within associated hydro pneumothorax fluid level . The sizable bleb seen at the upper edge of the right lung on the prior study is not now visualized , but this may be due to changes in the configuration of the lung as it expands . Again seen are sutures at the left lung apex in this the patient with a known history or prior left - sided pneumothorax .
    OUTPUT:
    
Continuing re-expansion of the right lung , with interval decrease in size of the right apical and right base pneumothoraces and improvement in the right base atelectasis . As before , there is actually a hydro pneumothorax at the right base , with a small right base pleural effusion .
