Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lungs are hyperinflated and the diaphragms are flattened , consistent with COPD . Heart size is at the upper limits of normal or slightly enlarged . Aorta is tortuous and unfolded . There is upper zone redistribution , without overt CHF . No focal consolidation and no effusion . On the lateral view , there is equivocal crowding of vessels in the infrahilar region , likely corresponding to some patchy opacity in the right cardiophrenic region . No pneumothorax . Old healed right lateral ___ and 12th ribs fractures noted . At the edge of these images , the left AC joint appears disrupted and there is ossification along the coracoclavicular ligament , likely sequela of remote trauma . Clips noted in the upper abdomen .
    OUTPUT:
    
Patchy opacity in the right cardiophrenic region and in the infrahilar region on the lateral radiograph is most consistent with atelectasis , however clinical correlation is recommended to assess for superimposed infection . s
