Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Large right hydropneumothorax is again demonstrated with a large pleural effusion component , perhaps minimally increased in size from the prior study , and an unchanged small right apical pneumothorax component . Right basilar opacification likely reflects compressive atelectasis . Mild shift of midline structures towards the left appears to be new . Left - sided pacemaker device is noted with single lead terminating in the region of the right ventricle . Heart size is difficult to assess given the presence of a large right pleural effusion , but appears mildly enlarged . The aorta is slightly unfolded . No overt pulmonary edema is seen . There is minimal atelectasis in the left lung base . No displaced fractures are noted .
    OUTPUT:
    
Large right hydropneumothorax with a large pleural effusion component , perhaps minimally increased in size , and unchanged small right apical pneumothorax component .
