    INPUT: A bedside AP radiograph of the chest demonstrates interval clearance of the large right pleural effusion with diffuse opacification of the right middle and lower lobes , likely secondary to re-expansion atelectasis . There is now a new small left pleural effusion which was not present four days ago . There is no pneumothorax . Cardiomegaly is stable . Interval widening of the upper mediastinal silhouette secondary to central venous engorgement is suggestive of hypervolemia . There is no pulmonary edema . A right chest wall central venous catheter is appropriately positioned in the lower SVC . The right chest tube is also appropriately positioned , in the right lower pleural space , including the side port .
    OUTPUT:
    
1 . The chest tube is appropriately positioned and there is no pneumothorax . 2 . Interval clearance of large right pleural effusion with re-expansion atelectasis of the right middle and lower lobes . 3 . New small left pleural effusion not present on the prior study . 4 . Findings suggestive of mild hypervolemia .
