乳腺纤维腺瘤的高频声像图表现及彩色多普勒血流显像分析

目的对乳腺纤维腺瘤高频声像图与CDFI的表现进行探讨。方法对75例经手术、病理证实为乳腺纤维腺瘤的高频声像图与CDFI表现进行了回顾性分析并与病理作了一些对照。结果典型的乳腺纤维腺瘤表现为边界清晰、规则光整的椭圆形或圆形肿块，有纤细的包膜回声及侧壁声影，而非典型的乳腺纤维腺瘤可表现为分叶状、形态、边界不规则、毛糙、有角状突起，无明显包膜及侧壁声影，肿块内可出现条索状强光带及钙化回声，压之与周围组织无明显逆向运动。本组血流信号检出率为57.4%(43/75)，平均最大流速(14±9.17)cm/s，平均最小流速(4.16±2.9)cm/s，平均RI0.70±0.12。结论乳腺纤维腺瘤部分表现为较典型的图像，诊断符合率高，但部分纤维腺瘤图像表现不典型，较易误诊，通过总结、分析、认识，诊断符合率有望进一步提高。

Evaluation of High Frequency Ultrasonography and CDFI in Diagnosis of Fibroadenoma of Breast

Objective:To evaluate the diagnostic role of high frequency ultrasonography (HFU)and CDFI for breast fibroadenoma of both the male and the female.Methods：HFU and CDFI findings were reviewed and compared with pathologic study in 75 cases confirmed with fibroadenoma of breast.Results:The typical imaging findings of fibroadenoma were in elliptical or round shapes with homogeneous internal echo,and were marginated smoothly with a fine echoic capsule and a lateral wall shadowing.The nontypical imaging findings of fibroadenoma were lobulated,irregular,angular without a capsule and lateral shadowing.The internal echo of the tumor showed hard light strips and calcification.The tumor and its surrounding tissues had no backward movements by pressure,Vmax was (14±9.17)cm/s,Vmin was (4.16±2.9)cm/s，RI was 0.70±0.12.Conclusions:Part of imagings of breast fibroadenoma are typical,the diagnosis rate corresponding with pathology is very high.Part of imagings are not typical,and misdiagnosis rate shall be further improved.
