彩色多普勒超声在乳腺单纯性黏液腺癌与纤维腺瘤鉴别诊断中的价值

目的 探讨彩色多普勒超声在乳腺单纯性黏液腺癌与纤维腺瘤鉴别诊断中的价值.方法 对25例乳腺单纯性黏液腺癌与30例纤维腺瘤患者进行彩色多普勒超声检查,分析病灶的声像图表现、内部和周边的血流分布及多普勒频谱,将诊断结果与病理结果进行对照.结果 彩色多普勒超声对乳腺单纯性黏液腺癌与纤维腺瘤诊断的符合率分别为76.0%、93.3%,90%纤维腺瘤可见清晰包膜,内部回声均匀,单纯性黏液腺癌则无包膜,内部回声大多杂乱不均;纤维腺瘤Ⅰ～Ⅱ级血流检出率仅为40%,而单纯性黏液腺癌Ⅰ～Ⅲ级血流检出率高达76%,二者的血流分级和阻力指数(RI)差异均有显著统计学意义.结论 彩色多普勒超声在乳腺单纯性黏液腺癌与纤维腺瘤的鉴别诊断中具有重要的临床价值.

Value of color Doppler ultrasonography in differential diagnosis of pure mucinous adenocarcinoma and adenofibroma of breast

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.
