Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A dual - lead pacemaker / ICD device appears in unchanged . The heart is probably normal in size but not well imaged because of overlapping opacities . The aortic arch appears calcified . In the right lung , there is diffuse mild opacification that is confluent near the base of the lung with layering opacity suggesting a substantial pleural effusion is likely present . Increased interstitial opacification is also noted along the right mid-to - lower lung . In the left lung , mostly aeration is good in the mid to upper lungs , but at the left lung base , there is also confluent retrocardiac opacity . No definite pleural effusion is seen on the left side .
    OUTPUT:
    
Multifocal opacities , much more extensive in the right lung than left , which may represent extensive pneumonia in the appropriate clinical setting , including a moderate suspected right - sided pleural effusion .
