Further Evaluation By Ultrasound Of Mammographically Determined Breast Dysplasia

Evaluation of 135 consecutive patients was made for breast masses by the same surgeon and the patients were subsequently referred for ultrasound mammography of the breast after xeromammography revealed a "dysplastic" (DY) pattern only, with no evidence of malignancy. Three patients had carcinoma of the breast detected by ultrasound mammography that had been missed by xeromammography. Two of the three cancers were similarly diagnosed by fine-needle aspiration cytology. All patients with a normal ultrasound examination have now been followed for a minimum of 15 months without evidence of developing breast cancer. This study confirms the importance of using additional diagnostic modalities for evaluating patients with dysplastic breasts and strongly suggests the value of ultrasound mammography in this group of patients.
