目的：分析不典型乳腺纤维腺瘤的二维及彩色多普勒声像图特征，探讨超声误诊原因。方法对25例经手术病理证实为乳腺纤维腺瘤，超声误诊为乳腺恶性肿块的二维及彩色多普勒声像特征进行回顾性分析。结果不典型乳腺纤维腺瘤二维表现呈分叶状，形态不规则，可见角状突起，无明显包膜，部分内部可见强回声钙化灶及后方可见声衰减。血流信号检出率为64%(16/25)，阻力指数范围0.5~0.8。结论不典型乳腺纤维腺瘤复杂多样，单凭超声图像较易与恶性肿块产生重叠现象，需结合患者病史、肿块声像特征、血流分布、阻力指数及有无微钙化灶进行综合性分析，才能减少超声误诊率。

Objective To analysis of two dimensional (2D) and color doppler ultrasonographic features in atypical breast fibroadenoma and to evaluate the causes that the patients were misdiagnosised as the atypical breast fi-broadenoma with ultrasound. Methods We had used a retrospective study, to analysis the causes that 25 patients had received surgical treatment and had definite pathological diagnosis but they were misdiagnosised as breast tumor with 2D and color doppler ultrasound. Results The ultrasonographic features is showed vary feature in breast fibroadeno-ma, which include lobulation,irregular shape,an unclear capsule, speculate, small enhancement calcification in mass, ultrasonic attennation behind mass. The positive rate of the breast fibroadenoma with ascularized mass were detected with ultrasound was 64%(16/25). Resistance index range were 0.5~0.8. Conclusion The ultrasound imaging in the breast fibroadenoma are diverse, in order to reduce its misdiagnosing rate,we should pay attention to the sonographic overlapping of different breast masses, reliance on history and ultrasonic signs and blood flow distribution and resis-tance indexis often needed.
