Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size is normal . Bilateral healed rib fractures have developed since the prior radiograph with a marked callus formation at the fracture sites . A focal opacity overlying the right tenth posterior rib level could also potentially be due to healed fracture , but it is difficult to distinguish from a focal area of pneumonic consolidation . Lungs are otherwise clear , and there are no pleural effusions .
    OUTPUT:
    
Focal opacity at right tenth posterior rib level , which could be due to callus from a healed fracture or an early focus of pneumonia . Short - term followup chest radiographs may be helpful in this regard .
