[The role of echography in the determination and monitoring of ductal ectasia in nipple discharge].

In this study a good sensibility of ultrasound in identifying ductal disease was demonstrated. We evaluated the relationship between nipple discharge and ductal ectasia and the importance of the ectasia in maintaining nipple discharge. From our data the hypothesis of a possible role of oestroprogestinic hormones in the genesis or maintaining of ductal ectasia emerged.
