There is persistent opacification obscuring the left costophrenic angle . This may represent pneumonia but with no short - term change . A trace pleural effusion is difficult to exclude on the left side .
    OUTPUT:
    
Persistent opacity in the lateral left lower lung , possible pneumonia . Follow - up radiographs are suggested to show resolution . Large hiatal hernia . New central venous catheter terminating in the superior vena cava ; no evidence of pneumothorax .
