Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Redemonstrated is a small right apical pneumothorax measuring up to 1 .4 cm vertical diameter stable from the prior exam . Mild pulmonary edema is new and moderate cardiomegaly has increased Right lower lobe atelectasis is noted . Small right pleural effusion is stable . Interval increase in fullness along the inferior aspect of the aortic arch is likely secondary to patient positioning , but warrants attention on follow up .
    OUTPUT:
    
1 . Stable , 1 .4 cm right apical pneumothorax and small dependent pleural effusion . 2 . Interval worsening of moderate cardiomegaly accompanies new mild pulmonary edema . 3 . Increased opacity within the aorticopulmonary window . Findings are likely secondary to differences in patient positioning , but repeat chest radiographs are recommended to document the stability of this finding .
