【摘要】：目的观察含有鳞状细胞癌成分的乳腺化生性癌(MCSC)的声像图和病理学特征。方法回顾性分析7例经手术病理检查证实的MCSC患者的二维声像图及CDFI声像图特征,并与病理学表现进行对照分析。结果 7例MCSC病灶均为单发;最大径2.6~5.1cm;6例为混合回声,1例为低回声,6例病灶内均可见大小不一的无回声区;7例形态均呈微小或小分叶状、边缘模糊。CDFI显示病灶实性部分有较丰富血流,4例为Ⅲ级血流信号,2例为Ⅱ级血流信号,1例为Ⅰ级血流信号,频谱显示为高阻力动脉血流(阻力指数0.75~0.97)。术后病理大体标本示6例为囊实性,1例为实性,镜下病理5例表现为腺鳞癌,2例表现为纯鳞状细胞癌。免疫组化显示雌、孕激素受体和人表皮生长因子受体均为阴性者(三阴乳腺癌)4例。结论 MCSC声像图特征为体积较大、囊实性混合回声、瘤体后方回声增强、实性回声内血供丰富且动脉阻力高。
[Abstract]:Objective to observe the sonographic and pathological features of MCSCs containing squamous cell carcinoma (SCC).Methods the features of two-dimensional sonogram and CDFI sonogram in 7 patients with MCSC confirmed by operation and pathology were analyzed retrospectively and compared with pathological findings.Results in 7 cases of MCSC, the lesions were all single, and the maximum diameter of 2.6 ~ 5.1 cm ~ (-1) was mixed echo in 6 cases. In 6 cases of hypoechoic lesions, 7 cases showed small or small lobular anechoic areas with different sizes.The margin was blurred. CDFI showed abundant blood flow in the solid part of the lesion. 4 cases were grade 鈪，
