Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A dual - lead pacemaker / ICD device appears unchanged . The heart is mild to moderately enlarged . The mediastinal contours are stable including a large hiatal hernia . There is a new or increased small right - sided pleural effusion with lateral right - sided pleural thickening , suggestive of a degree of loculation of pleural fluid or new pleural thickening . The pulmonary interstitium is again prominent . There is new widespread opacification in the right lung , particularly in the right upper lobe . Although the possibility of atypical pulmonary edema could be considered for this appearance , this degree of asymmetry would be more typical for an infectious process . Correlation with clinical presentation and laboratory data is recommended .
    OUTPUT:
    
New opacities in the right lung , worrisome for pneumonia .
