非哺乳期乳腺炎与乳腺癌的超声特点对比

Contrast of ultrasonic characteristics between non-lactating mastitis and breast cancer

目的对比分析非哺乳期乳腺炎与乳腺癌患者的超声特征。方法选取2014年6月~2015年9月我院收治的非哺乳期乳腺炎患者37例为A组,另选同期收治的乳腺癌患者34例为B组,两组患者均经病理检验证实,术前均接受彩色多普勒超声检查,观察两组患者肿块声像图表现。结果 A组患者术前超声诊断显示15例为2级,14例为3级,8例误诊为4级;B组患者术前超声诊断显示8例为3级,26例为4级。两组患者肿块血供、边界清晰度、后方衰减、左右分布比较,差异无统计学意义(P>0.05);两组患者肿块微小钙化、血流阻力指数、纵横比、腋窝淋巴结肿大、局部液化比较,差异有统计学意义(P<0.01)。结论乳腺癌与非哺乳期乳腺炎声像图表现部分相似,但其肿块微小钙化、血流阻力指数、纵横比、腋窝淋巴结、局部液化情况各有特点,可为疾病的鉴别、诊断提供重要参考。

Objective To compare and analyze ultrasonic characteristics between non-lactating mastitis and breast cancer. Methods 37 cases of.patients with non-lactating mastitis treated in our hospital from June 2014 to September 2015 were selected as group A and at the same time 34 cases of patients with breast cancer were selected as group B.AI1 pa- tients in two groups were confirmed by pathological examination and preoperative color Doppler ultrasound examination was performed to observe the sonographic appearance of tumor in the patients in two groups.Results In group A,among patients with preoperative ultrasound diagnosis 15 cases were grade 2,14 cases were grade 3 and 8 cases were misdiag- nosed as grade 4,while in group B,patients with preoperative ultrasound diagnosis showed that there were 8 cases in grade 3 and 26 cases in grade 4.There was no statistical significance in mass blood supply,boundary definition,rear at- tenuation and lift and right distribution in two groups （P〉0.05）.The differences of micro calcification of tumor,blood flow resistance index,aspect ratio,axillary lymph node enlargement and local liquefaction in two groups had statistical signifi- cance （P〈0.01）.Conclusion The ultrasonic imaging characteristics of breast cancer and non-lactating mastitis are partly similar,but the micro calcification of tumor,blood flow resistance index,aspect ratio,axillary lymph node enlargement and local liquefaction condition have different characteristics,which can provide an important reference for disease identifi- cation and diagnosis.
