【摘要】：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(P0.05)。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。
[Abstract]:Objective to investigate the (MBC) findings of breast mucinous adenocarcinoma and its relationship with pathological features. Methods 37 cases of MBC confirmed by operation and pathology in our hospital were analyzed retrospectively. The relationship between ultrasound findings and pathological features of MBC was analyzed. Results (1) among 37 cases of MBC, 19 cases were simple type, 18 cases were mixed type. All mixed type were MBC and invasive ductal carcinoma. (2) in 78.4% of MBC masses, 43.2% of the masses were irregular in shape and 8.1% in the aspect ratio of the masses. There were 21.6% of the masses with non-echoic areas (or liquefaction areas) in the masses with non-echoic areas (or liquefaction areas) in 21.6% of the masses. (2) the sonographic manifestations of the masses were as follows: 43.2% of the masses with boundary clearance, 43.2% of the masses with irregular shape and 8.1% of the masses with a aspect ratio of 鈮，
