Résumé
Objective To investigate the mammographic,galactographic,pneumographic features and their pathological basis.Methods Mammography(n=26),galactography(n=13),pneumography(n=5)and specimen radiography(n=12) in 26 cases pathologically proved,and mammographic-pathologic correlation were analyzed.Results The breast hamartomas in 26 cases were all benign,they were circumscribed and surrounded by a true capsule.The mammographic appearances could be divided into three types acording to different amount of fibroglandular and adipose tissue in tumors:prominantly fatty,prominantly fibrous(fibroglandular)and mixed fibrofatty.Conclusion A clearly containing areas of fat and fibroglandular density and a characteristic"slice of sausage"appearance can be showed on mammograms.Galactography and pneumography is of a great help to differential diagnosis of breast hamartomas.
