    INPUT: The upper lobe pulmonary veins are full , as before . There is interval blunting of the costophrenic angles . There is minimal hazy density at the left base only well seen on the PA view . The lungs are otherwise clear . The heart is at the upper limit of normal in size . The aorta is calcified . Mediastinal structures are otherwise unremarkable . The bony thorax is grossly intact .
    OUTPUT:
    
Development of small bilateral pleural effusions . Continued evidence of mild pulmonary venous hypertension . Ill - defined increased density at the left base may be due to pleural fluid . A small area of focal consolidation can not definitely be excluded .
