Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral views of the chest were obtained . Lungs are clear and hyperinflated without focal consolidation , effusion , or pneumothorax . Given the hyperinflation and slight coarsening of reticular markings in the lungs , the likelihood of underlying emphysema is raised . A lucency along the medial right upper lung could reflect a large bulla . There is no pneumothorax . Cardiomediastinal silhouette appears grossly unremarkable . Bony structures are intact .
    OUTPUT:
    
Emphysema with prominent bulla in the right upper lung . No signs of fracture or pneumothorax .
