Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lungs are hyperinflated . A vague rounded opacity in the right base is consistent with a nipple shadow . The pulmonary vasculature is indistinct , compatible with pulmonary vascular congestion . No overt pulmonary edema or pleural effusion is noted . No focal pulmonary consolidation or pneumothorax . The heart size is normal . Osseous structures are unremarkable . No radiopaque foreign body .
    OUTPUT:
    
1 . Pulmonary vascular congestion without effusion . 2 . Rounded opacity in the right lung base is likely a nipple shadow , but follow - up radiograph with nipple markers may be obtained for confirmation after diuresis .
