摘要 [目的]探讨三阴性乳腺癌的超声图像特征。[方法]总结45例三阴性乳腺癌超声图像特征,并与76例非三阴性乳腺癌的超声图像进行对比。[结果]微钙化、肿瘤后方回声衰减、周边高回声晕的超声表现在三阴性乳腺癌中分别占13.33%(6/45)、13.33%(6/45)、6.67%(3/45),在非三阴性乳腺癌中分别占56.58%(43/76)、52.63%(40/76)、42.11%(32/76),两组间比较差异有统计学意义(P<0.05)。纵横比≥1、肿块内部回声分布不均匀、毛刺(蟹足)征及血流分布状况两组间比较差异无统计学意义(P>0.05)。肿块≤20mm的三阴性乳腺癌腋窝淋巴结转移率较非三阴性乳腺癌腋窝淋巴结转移率高。[结论]三阴性乳腺癌在超声图像上无特征性表现,特别是当肿瘤<20mm时难与良性肿瘤鉴别,应结合腋窝淋巴结情况综合评估。
