Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs are hyperinflated with an increased AP diameter , which is likely exaggerated by the thoracic spine kyphosis . Heart size is moderately enlarged but stable . There is no focal consolidation , pulmonary edema or pneumothorax . Blunting of the costophrenic angles bilaterally is likely a function of small pleural effusions , better characterized on the CT from the same day . A significantly calcified aortic knob is again noted .
    OUTPUT:
    
1 . Stable moderate cardiomegaly . 2 . Hyperinflated lungs consistent with underlying emphysema . 3 . No evidence of pneumonia . 4 . Trace bilateral pleural effusions . 5 . Please refer to same - day CT for evaluation of traumatic injury to the chest .
