    INPUT: Portable upright chest radiograph ___ at 09 :08 is submitted .

There is a questionable tiny lucency near the right apex which could reflect a very tiny pneumothorax or possibly loculated air or focal pleural fat as no definite pleural line is seen extending from this lucency . Clinical correlation is recommended . Residual patchy opacity at the right base likely reflects atelectasis . Improved aeration at the left base . No pulmonary edema . Overall cardiac and mediastinal contours are stable given differences in patient rotation .
