Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiomediastinal silhouettes are normal . The bilateral hila are normal . There is a circular opacity projecting over the left lower lung which is well circumscribed and most likely represents left nipple , less likely left lower lung true parenchymal lesion . There is no definitive lower lung lesion seen on lateral view . Given clinical indication for chest x-ray , it is recommended to obtain repeat PA x-ray with bilateral shallow oblique views and nipple markers . There are no other focal lung consolidations . There is no pulmonary vascular congestion or pulmonary edema . There is no pneumothorax or effusion .
    OUTPUT:
    
Well - circumscribed circular opacity projecting over left lower lung , most likely represents left nipple , less likely a true left lower lung nodule . Recommend repeat PA with bilateral oblique views and nipple markers . Otherwise unremarkable chest x-ray .
