There is improved aeration of the bilateral lung bases with persistent mild bilateral infrahilar opacification with air bronchograms on the right . No pneumothorax is present .
    OUTPUT:
    
Improved aeration of the bilateral lung bases with persistent infrahilar opacities may reflect improved pulmonary edema .
