Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient has been extubated . A nasogastric tube terminates in the stomach . A right internal jugular central venous catheter terminates in the lower superior vena cava . Although an opacity has partly resolved in the right lower lung , probably in the right lower lobe , there is a marked increase in retrocardiac opacification reflecting atelectasis or consolidation of the left lower lobe including air bronchograms . Associated volume loss is suspected with new shift of mediastinal structures towards the left . There is no pneumothorax .
    OUTPUT:
    
Increase in opacification and volume loss in the left lower lobe . Improving right basilar opacification . Status post endotracheal extubation .
