    INPUT: Frontal radiograph demonstrates interval worsening of bilateral hazy opacifications in the lung bases which is likely due to worsening pulmonary edema . There is also an increase in right pleural effusion with fluid seen tracking along the oblique fissure . There is no pneumothorax . There is an ill - defined hazy opacity in the right upper lung which is seen on previous radiographs and may represent an area of scarring , however this should be correlated clinically . The heart size is not significantly changed since the prior study .
    OUTPUT:
    
Interval worsening of bilateral pulmonary edema and right pleural effusion . Previously seen right upper lung opacity may represent an area of scarring and should be correlated clinically .
