Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Cardiac silhouette is mildly enlarged but has decreased in size compared to the prior study . Pulmonary vascular congestion has also improved , along with rapidly improving right upper juxtahilar opacity , with some residual predominantly linear opacities remaining in this region . Minimal linear areas of atelectasis are demonstrated in the lingula and left lower lobe , and note is also made of small bilateral pleural effusions . Permanent pacemaker remains in standard position with leads in right atrium and right ventricle .
    OUTPUT:
    
Improving pulmonary vascular congestion . Rapidly resolving right juxtahilar opacity , favoring either asymmetrical edema or acute aspiration over an infectious pneumonia . Continued radiographic followup may be helpful to document complete resolution .
