Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart appears mildly enlarged . The aortic arch is calcified and perhaps mildly ectatic . There is no pleural effusion or pneumothorax . A right perihilar opacity , not well seen on the lateral view but probably involving the right upper lobe , is suggestive of pneumonia , although not entirely a specific finding . Aside from streaky opacities in the right lower lung , otherwise the lung fields appear fairly clear . The bones appear demineralized .
    OUTPUT:
    
Right upper lung opacity suggesting pneumonia . However , coinciding malignancy , or malignancy mimicking pneumonia , should be excluded by performing short - term follow - up radiography within six to eight weeks in order to show resolution of the finding .
