    INPUT: The lungs are clear without consolidation or edema . There is no pleural effusion or pneumothorax . The heart is mildly enlarged . The mediastinal contours are normal . Irregular contours of the posterior left eighth and ninth ribs are suspicious for possible non-displaced rib fractures . A similar abnormal contour in the posterior right seventh rib is also suspicious for a possible fracture . There is a mild compression deformity in the lower thoracic spine of indeterminate age . No other compression fractures are identified .
    OUTPUT:
    
1 . Possible fractures of the left posterior eight and ninth ribs and right posterior seventh rib , but no pneumothorax of pleural effusion . 2 . Mild compression deformity in the lower thoracic spine of indeterminate age , though likely chronic . If there is high clinical suspicion for an acute compression fracture , could be evaluated with a non-contrast CT .
