Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single frontal view of the chest was obtained . Heterogeneous opacification of the right lung is increased with increased involvement of the right lower lung . Right upper lobe involvement appears stable . Pulmonary edema is slightly improved . Left pleural effusion has decreased in size . No pneumothorax . Mild cardiomegaly is unchanged . Moderate hiatal hernia is chronic . No radiopaque foreign body .
    OUTPUT:
    
1 . Increased heterogeneous opacity of the right lower lung with unchanged involvement of the right upper lung likely reflects worsening infection or pulmonary hemorrhage . 2 . Improved pulmonary edema with decreased size of left pleural effusion .
