乳腺黏液癌30例的超声图像分析

目的 评价超声对乳腺黏液癌的诊断价值.方法 对手术病理证实的30例乳腺黏液癌的超声图像进行分析,分析内容包括边缘形态、内部回声、血流显像等.结果 乳腺黏液癌超声声像图表现为:边缘清(93%,28/30),形态较规则(67%,20/30),低回声不均质团块(90%,27/30),纵横比≤0.77(83%,25/30),内部血流稀少(0级22例,1级8例),后方回声轻度增强21例;超声诊断与病理诊断相符16例(53%);病理为乳腺黏液癌,而超声诊断为其它良性病变5例(17%);超声诊断为未定性实质团块,而病理为乳腺黏液癌9例(30%).结论 乳腺黏液癌恶性特征不明显,超声容易漏诊误诊,尤其是单纯型.

Ultrasound images of mucinous carcinoma in breast: Analysis of 30 cases

To evaluate the diagnostic value of ultrasonography in mucinous carcinoma in breast. Thirty cases of mucinous carcinoma in breast confirmed by operation were analyzed and reviewed.The edges and borders,internal echo and blood flow display were observed. The sonographic appearance showed 28 cases（93%）with distinct boundary,20 cases（67%）with regular modality,27 cases（90%）with heterogeneous hypoechoic mass,25 cases（83%）with aspect ratio less than 0.77,22 cases with blood flow in grade 0,8 cases with blood flow in grade 1,and 21 cases with mild enhancement in posterior echo.The diagnosis rate was 53%（16/30）.The misdiagnosis rate was 17%（5/30）.The undetermined rate was 30%（9/30）. The malignant features of mucinous carcinoma in breast for ultrasound are unconspicuous,which may lead to misseddiagnosis and misdiagnosis,especially for the simple type.
