Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP upright and lateral chest radiographs were obtained . The patient is markedly rotated and kyphotic which likely in part accounts for the prominence of the superior mediastinum . In addition patient has a known right thyroid goiter . Allowing for this , the lungs appear clear with blunting of the bilateral costophrenic sulci potentially related to overlying soft tissue or pleural thickening particularly given the presence of numerous bilateral old rib fractures . However , there is a retrocardiac opacity which is more pronounced than on the prior study . This could reflect left lower lobe atelectasis ; however a left lower lobe pneumonia is also possible . Profound collapse of two mid thoracic spine vertebral bodies is seen with hyperdense material within 1 of them consistent with prior vertebroplasty . The heart remains mildly enlarged with calcified and tortuous aortic contour .
    OUTPUT:
    
Limited examination . Retrocardiac opacity suggestive of atelectasis or infectious process . Given this limitation , a repeat evaluation is recommended with conventional PA and lateral chest radiographs obtained at optimal inspiration if possible . These findings were discussed in person with Dr . ___ by Dr . ___ at ___ on ___ .
