    INPUT: There is mild to moderate pulmonary edema . On the lateral view , there is increased opacity projecting over the mid to lower thoracic spine and descending thoracic aorta . This may correspond to increased opacity projecting over the right hilar region on the frontal view . Degree of cardiomegaly which is moderate is similar compared to prior . Median sternotomy wires are noted . Dense atherosclerotic calcifications are noted in the thoracic aorta .
    OUTPUT:
    
Mild to moderate pulmonary edema . Opacity on the lateral view projecting over the spine . This could be due to superimposed structures ( spine , aorta ) with superimposed edema although superimposed consolidation from infection or underlying lesion are also possible . Followup will be necessary after treatment for acute issues to ensure resolution .
