    INPUT: Heart size remains mildly enlarged . The mediastinal and hilar contours are unremarkable . The pulmonary vasculature is not engorged . 5 mm nodular density projecting over the left lung base remains unchanged , and no focal consolidation is demonstrated . Streaky atelectasis is seen in the left lung base . Lungs are hyperinflated . No pleural effusion or pneumothorax is identified . The bones are diffusely demineralized . Surgical clip is noted in the right upper quadrant of the abdomen .
    OUTPUT:
    
Streaky left basilar atelectasis . Unchanged 5 mm nodular opacity projecting over the left lung base . Again this could be projectional artifact or reflect a small nodule . Consider CT for further assessment if there is high clinical concern .
