Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size is enlarged . There is increased opacity diffusely in the right greater than left lung . There is no pneumothorax . Blunting of the left costophrenic angle likely secondary to a pleural effusion . Convexity of the main pulmonary artery contour or as well as widening of the right mediastinal and bilateral hilar contours is also demonstrated .
    OUTPUT:
    
Cardiomegaly , enlarged main pulmonary trunk , and diffuse right greater than left lung opacities , findings favor moderate to severe pulmonary edema . Given asymmetry in lung opacity , pneumonia can not be excluded . Followup PA and lateral radiographs are recommended after diuresis to evaluate for underlying infection and to reassess mediastinal and hilar contours to help differentiate engorged vessels from lymphadenopathy he sought .
