摘要
目的:探讨不同病理类型乳腺黏液癌(mucinous breast carcinoma,MBC)的超声声像图特征。方法:回顾性分析38例经手术后病理证实为MBC,且有完整超声检查资料患者的临床资料,分析单纯型乳腺黏液癌(pure mucinous breast carcinoma,PMBC)和混合型乳腺黏液癌(mixed mucinous breast carcinoma,MMBC)超声特征之间的差异。结果:两组患者在肿瘤形态、边界、内部回声、后方回声、血流信号Adler分级、弹性评分等方面存在差异(均P<0.05)。而在肿瘤部位、边缘、瘤内钙化及腋窝淋巴结转移、瘤内峰值血流速度和阻力指数(resistance index,RI)之间差异均无统计学意义(均P>0.05)。结论:PMBC和MMBC超声特征和肿瘤良恶性诊断方面存在差异,PMBC易误诊为良性病变,因此,高龄女性乳腺内发现中等回声、后方回声增强、突向脂肪层膨胀性生长且弹性评分较低、RI较高的肿块时,超声医师应考虑到黏液癌的可能。
Objective:To analyze the ultrasonic characteristics of different pathological types of mucinous breast adenocarcinoma(MBC).Methods:Clinical and sonographic data of 38 patients with MBC confirmed by postoperative pathology were analyzed retrospectively,and the differences between ultrasonic characteristics of pure MBC(PMBC)and those of mixed MBC(MMBC)were analyzed.Results:There were significant differences in tumor morphology,tumor boundary,internal echo,posterior echo,Adler grade of blood flow signal,elasticity score and grade of malignancy between the two groups(P<0.05);but there were no significant differences in tumor site,tumor margin,intratumoral calcification,axillary lymph node metastasis,peak blood flow velocity and resistance index between the two groups(P>0.05).Conclusion:PMBC and MMBC are different in ultrasound characteristics and grade of malignancy.PMBC is easy to be misdiagnosed as benign lesions.When breast masses extending to fat layer with moder-ate echo,enhanced posterior echo,low elasticity score and high resistance index are found in breasts,the possibility of mucinous carcinoma should be considered.
