Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Cardiomediastinal contours are normal . Permanent pacemaker is present with leads in the right atrium and right ventricle . Lungs demonstrate biapical scarring as well as a vague 8 mm diameter right upper lobe opacity , possibly corresponding to an area of increased extrapleural fat and adjacent scarring in this region on recent PET - CT . There are no pleural effusions . Bones are diffusely demineralized , and note is made of mild compression deformity in the lower thoracic spine .
    OUTPUT:
    
No definite pneumonia . Vague 8 mm opacity in right upper lobe is potentially due to scarring , but a short - term followup radiograph may be helpful to exclude an early focus of pneumonia in this region if warranted clinically .
