Value of color Doppler ultrasonography in differential diagnosis of pure mucinous adenocarcinoma and adenofibroma of breast / 中华超声影像学杂志

ABSTRACT

Objective To probe the value of color Doppler ultrasonography (CDU) in differential diagnosis of the pure mucinous adenocarcinoma of breast (PMAB) and adenofibroma of breast (AFB).Methods Twenty-five cases of PMAB and 30 cases AFB were examined by CDU. The sonographic appearance, interior and peripheral blood flow distribution and Doppler frequency of the tumors were observed and analyzed. The results of the diagnoses of CDU and the pathologies were compared. Results The diagnostic rates of PMAB and AFB by CDU were 76.0% and 93.3%, respectively. The clear peplos was observed in 90% of AFB, and internal even echoes. Yet no peplos was observed in PMAB, and the internal echoes of most PMAB were confused and disordered. The detection rate of Ⅰ ～ Ⅱ stage blood flow in adenofibroma of breast was only 40% and that of Ⅰ ～ Ⅲ stage blood flow in PMAB was high to 76%.The detection rate of blood flow stage and the resistant index (RI) of the blood flow frequency spectrum of PMAB and AFB were significantly different. Conclusions CDU has significant clinical value in differential diagnosis of pure mucinous adenocarcinoma and adenofibroma of breast.
