    INPUT: The heart is normal in size . The aorta is again moderately tortuous with patchy calcification . Streaky left basilar opacity suggests minor atelectasis or scarring in the left lower lobe . There is a small suspected left - sided pleural effusion . There are mildly displaced fractures involving the anterior left second through fifth ribs . There is displacement among left anterior second , third , and fifth fractures by nearly a half shaft width . These show vague sclerosis , particularly the fifth , suggesting callus , but without complete remodeling .
    OUTPUT:
    
Multiple rib fractures , including three mildly displaced fractures with suspected early callus formation . Small left - sided pleural effusion .
