Ultrasonographic findings of accessory breast

Abstract

Accessory breast is an ectopic breast tissue from developemental remnants. It sometimes begins to make symptoms, pain and swelling, during premenstrual period or pregnancy. For it has been known as a rere condition, it has occasionally misdiagnosed as a abnormal mass, such as lymphadenitis or hidradenitis. We have analyzed 52 accessory breast tissues prospectively, to document the characteristic findings of accessory breast. In summary, the characteristic sonographic findings of accessory breast were the presence of breast tissue superficial to the axillary fascia or underlying fascia if not in axilla, resembling the patient's own breast pattern, the presence of converging appearance of dilated ducts, presence of nipple and/or areola, the obliteration of inner wall of dermis, the obliteration of sucutaneous fat layer, and the downward displacement of axillary fascia or underlying fascia if not in axilla wighout interruption.
