    INPUT: Heart size is mildly enlarged . Atherosclerotic calcifications are noted at the aortic knob . Pulmonary vasculature is indistinct , and there is diffuse parenchymal opacification in the right lung , as well as patchy opacity in the left lung base . No pleural effusion or pneumothorax is present . Moderate multilevel degenerative changes are seen in the thoracic spine .
    OUTPUT:
    
Diffuse parenchymal opacity in the right lung and patchy left basilar opacity along with vascular indistinctness , findings suggestive of asymmetric pulmonary edema . Multifocal infection , however , is not excluded in the correct clinical setting . Consider follow up radiographs after diuresis for further assessment .
