目的探讨乳腺黏液腺癌(MBC)的超声表现及其与病理特征的关系。方法回顾性分析我院37例经手术病理证实为MBC的声像图,分析MBC的超声表现与病理特征的关系。结果 (1)37例MBC中,单纯型19例,混合型18例,混合型全部是MBC与浸润性导管癌同时存在,其中MBC所占比例范围为2%~98%。(2)78.4%的MBC肿块超声表现为边界清,43.2%的肿块形态欠规则,8.1%的肿块纵横比≥1,51.4%的肿块内部回声不均匀,21.6%的肿块内部可见无回声区(或液化区),24.3%的肿块内部可见点状钙化,75.7%的肿块后方回声增强,62.2%的肿块内部无明显血流信号,13.5%的肿块出现腋下淋巴结转移。(3)乳腺单纯型MBC与混合型超声声像图比较,除边界(χ2=6.741,P=0.019)外,其余超声表现均无明显差异(P>0.05)。结论MBC因所含组织成分的不同,超声表现有所差异,但因其含有黏液,超声声像图常常表现为乳腺肿块内部回声欠均匀、后方回声增强、血流信号不明显。
Objective To investigate the ultrasonographic features of breast mucinous adenocarcinoma (MBC) and its relationship with pathological features. Methods A retrospective analysis of 37 cases of our hospital confirmed by pathology as MBC sonograms to analyze the relationship between MBC ultrasound findings and pathological features. Results (1) Of the 37 MBC cases, 19 were simple type and 18 were mixed type. All the mixed types were MBC with invasive ductal carcinoma, with the proportion of MBC ranging from 2% to 98%. (2) 78.4% of the MBC masses showed border clear, 43.2% of the masses had undefined shape, 8.1% of the masses had an aspect ratio of ≥1.51.4%, and 21.6% of the masses had an anechoic area Or liquefaction area). 24.3% of the masses showed punctate calcification, 75.7% of the posterior echoes were enhanced, 62.2% of the masses had no obvious blood flow signals, and 13.5% of the tumors showed underarm lymph node metastases. (3) There was no significant difference (P> 0.05) in other ultrasonographic features except the boundary (χ2 = 6.741, P = 0.019). Conclusion Ultrasound showed different results due to the different tissue components. However, because of the presence of mucus, the ultrasonographic features of MBC often show that the internal echo of the breast mass is not uniform, the posterior echo is enhanced, and the blood flow signal is not obvious.
