Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There are diffuse bilateral alveolar opacities , with relative sparing of the upper lung fields , with obscuration of the right and left heart borders as well as the bilateral hemidiaphragm margins . A dense opacification is also seen in the left apex , without tracheal deviation or obscuration of the left spine border . There is also significant irregular pleural thickening in the right apex , possibly secondary to layering pleural effusion . Right basilar plueral calcifications are noted . Cardiac size can not be assessed due to obscuration of the cardiac silhouette . There is no evidence of pneumothorax . Layering pleural effusions are possible . No fractures are identified .
    OUTPUT:
    
1 . Findings compatible with acute pulmonary edema with possible layering pleural effusions . Superimposed infectious / inflammatory process can not be excluded . 2 . Significant left apical density may represent a loculated pleural effusion versus a mass . Followup of this will be necessary after treatment .
