乳腺黏液癌的超声图像特征分析

目的对乳腺黏液癌的超声图像特征进行分析从而提高其超声诊断准确率。方法对14例手术病理证实为乳腺黏液癌患者的超声图像及其病理特征进行回顾性分析。结果 14例乳腺黏液癌术前超声诊断为乳腺恶性肿瘤8例,可疑恶性肿瘤5例,误诊为良性结节1例。14例黏液癌超声表现为纵径与横径比值均<1,多数单纯型黏液癌形态规则、内部回声不均、后方回声增强,单纯型黏液癌很少出现微钙化及晕征。混和型黏液癌形态多不规则、内部回声不均匀、后方回声衰减。CDFI示9例肿瘤周边或内部可见点条状血流信号,脉冲波多普勒显示血流阻力指数(RI)均>0.7。术后病理诊断单纯型黏液癌11例,均无腋窝淋巴结转移;混合型黏液癌3例,其中2例伴同侧腋窝淋巴结转移。结论不同病理类型乳腺黏液癌超声图像具有一定特征,认识这些特征有助于乳腺黏液癌的诊断。

Analysis on ultrasonographic features of breast mucinous carcinoma

Objective To analyze the ultrasonographic features of the breast mucinous carcinoma and to improve the accurate rate of ultrasound diagnosis. Methods The sonographic appearance and pathological feature of breast mucinous carcinoma in 14 patients diagnosed by operation and pathology were retrospectively analyzed. Their relationships were initially discussed between ultrasonography and corresponding pathological type. Results A total of 8 cases were diagnosed as breast malignant neoplasms; 5 cases were diagno...
