Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs remain hyperinflated , with relative flattening of the diaphragms . Subtle opacity is seen projecting over the lateral right lung base over the lateral right tenth rib . Unclear whether this represents a pulmonary nodular opacity versus being external to the patient . Shallow oblique chest radiographs would help further assess . There is mild left base atelectasis . No pleural effusion or pneumothorax is seen . The cardiac silhouette is top - normal . Mediastinal contours unremarkable . No pulmonary edema is seen .
    OUTPUT:
    
Subtle opacity projects over the lateral right lung base , over the lateral right tenth rib ; unclear whether this is external to the patient or represents a pulmonary nodular opacity . Recommend shallow oblique chest radiographs to further assess . No focal consolidation seen elsewhere .
