Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Again seen are 2 chest tubes at the base of the right lung , where a small pneumothorax is present . As before , there is some density at the base of the right lung parenchyma , likely atelectasis . Also as before , there is fluid and / or pleural thickening tracking from the lung apex down along the right chest wall . However , the right costophrenic angle remains well - defined , without interval accumulation of right pleural fluid . Otherwise , I doubt significant interval change . Minimal blunting of the left costophrenic angle is similar to the prior film .
    OUTPUT:
    
No significant change . Small pneumothorax at base of right lung is similar to the prior film .
