Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes remain extremely low . Left lower lobe opacity has increased , likely due to increasing pleural fluid ; though the overall opacity likely reflects a combination of atelectasis , known pleural mass and pleural fluid . A tiny left apical pneumothorax is stable . A left pleurX catheter terminates near the left hilum . Subcutaneous emphysema along the left chest wall is decreased .
    OUTPUT:
    
1 . Slightly increased left basilar opacity likely related to increasing pleural fluid . 2 . Left PleurX catheter terminating near the left hilum . 3 . Unchanged tiny left apical pneumothorax .
