摘要
目的探讨高频彩色多普勒超声对乳腺髓样癌的诊断价值。方法 56例乳腺髓样癌患者,均为女性,年龄25～87岁,平均年龄50.92岁;其中典型髓样癌35例,非典型髓样癌21例。患者手术前行乳腺超声检查,先用灰阶超声观察肿块的部位、大小、形态、边界、内部回声、有无钙化、后方回声增强或衰减,再启用彩色多普勒血流显像(CDFI)检查肿块的血流信号,频谱多普勒分析肿块血流阻力指数(RI),最后检查腋窝淋巴结有无肿大。结果乳腺髓样癌发生于左侧乳腺者占57.14%,高于右侧乳腺的42.86%,但差异无统计学意义(P>0.05)。典型髓样癌最大径平均值为2.39cm,略小于非典型髓样癌的2.52cm(P>0.05)。与非典型髓样癌比较,典型髓样癌形态较规则、边界较清楚、内部回声较均匀,多伴后方回声增强,钙化较少见。乳腺髓样癌血液供应多较丰富,该组32例典型髓样癌、18例非典型髓样癌进行了CDFI检查,血流Ⅱ/Ⅲ级者分别占65.63%、61.11%(P>0.05),其中20例进行了多普勒频谱分析,RI>0.70。结论典型髓样癌与非典型髓样癌在肿块的边界、回声均匀与否,有无钙化及后方回声增强等超声表现明显不同,术前高频彩色多普勒超声检查具有重要诊断价值。
Objective To investigate the diagnostic value of high frequency ultrasound on breast medullary carcinoma.Methods A total of 56 female breast medullary carcinoma patients were enrolled,aged 25-87 years old,mean age 50.92 years old.Thirty-five were typical and 21 were atypical.All of them received preoperative ultrasound examination.The mass location,size,shape,boundary,internal echo,calcification and posterior echo were observed by gray-scale mode ultrasound.After that,the mass blood supply was detected using color Doppler flow imaging（CDFI）,and the resistance index（RI） was measured by pulsed-wave Doppler.Results The incidence rate of medullary carcinoma in left breast was 57.14 %（32/56）,which was higher than that in the right（42.86 %,24/56）（P 0.05）.The mean maximum diameter of atypical medullary carcinoma（2.39 cm） was slightly smaller than that of the typical（2.52 cm）（P 0.05）.Compared with the atypical medullary carcinoma,the typical showed more regular shape,clear boundary,homogeneous internal echo,enhanced posterior echo,but less calcification.According to Doppler ultrasound examination,65.63 % typical and 61.11 % atypical medullary carcinoma displayed abundant blood flow,and 100.0 %（20/20） medullary carcinoma showed RI 0.70.Conclusion The high frequency color Doppler ultrasound showed different appearances between typical and atypical medullary carcinoma in mass boundary,internal echo,calcification and posterior echo,which would be a significant method for the disease diagnosis.
