Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Patient is status post left lower lobe resection . A moderate left hydropneumothorax has slightly decreased in size from the prior study . The apical pneumothorax component is now located between the fourth and fifth posterior ribs and was previously at the fifth posterior rib level . A substantial hydropneumothorax component in the lower left hemithorax on the prior study demonstrates increase in amount of fluid and decrease in amount of gas compared to the prior exam . Pigtail pleural catheter remains in place , terminating at the left apex . Right lung is hyperexpanded and demonstrates some bullous emphysema at the right lung apex .
    OUTPUT:
    
Moderate left hydropneumothorax , with slight decrease in size of apical pneumothorax component , and increased ratio of pleural fluid to pleural gas in the hydropneumothorax component in the lower left hemithorax . Improving opacities in the lingula may reflect resolving reexpansion pulmonary edema and less likely pulmonary infection .
