对比分析非哺乳期乳腺炎与乳腺浸润性导管癌的高频彩色多普勒超声表现

目的 比较非哺乳期乳腺炎与乳腺浸润性导管癌高频彩色多普勒超声的表现。方法 回顾性分析经病理检查证实的116例非哺乳期乳腺炎患者与115例乳腺浸润性导管癌患者（浸润性导管癌组）的高频彩色多普勒超声检查结果，其中116例非哺乳期乳腺炎患者正确诊断71例（非哺乳期乳腺炎组）、误诊为乳腺浸润性导管癌45例（误诊组），比较各组病灶的声像图表现。结果 非哺乳期乳腺炎组病灶声像图上多表现为形态规则、边界清晰、无回声及后方回声增强，与误诊组比较差异有统计学意义（P＜0.05）。非哺乳期乳腺炎组和浸润性导管癌组比较，前者声像图上多表现为形态规则、边界清晰、少斑点状强回声、无回声、少高回声、后方回声增强、少腋窝淋巴结肿大（P＜0.05）。误诊组与浸润性导管癌组声像图上均表现为形态不规则、边界不清晰、回声不均匀，并伴有丰富血流信号，但两者斑点状强回声（χ²=30.805，P<0.001）、高回声晕（χ²=20.282，P<0.001）、后方回声增强（χ²=6.442，P=0.011） 等表现比例差异有统计学意义。结论 高频彩色多普勒超声诊断非哺乳期乳腺炎易误诊为乳腺浸润性导管癌，注意观察斑点状强回声、高回声晕、后方回声增强等表现有助于正确诊断。

Comparison of high frequency color Doppler ultrasound features between infiltrating ductal carcinoma#br##br#and non-lactation mastitis#br#

Objective To compare the features of high frequency color Doppler ultrasound between infiltrating ductal carcinoma and non-lactation mastitis. Methods A total of 116 non-lactation mastitis cases（71 ultrasound-diagnosed non-lactation mastitis and 45 non-lactation mastitis misdiagnosed as cancer） and 115 infiltrating ductal carcinoma cases were analyzed retrospectively to compare their ultrasound features. Results Non-lactation mastitis group showed regular shape，clear boundary，no echo area，and posterior echo enhancement，and the difference was statistically significant compared with the misdiagnosed group（P<0.05）. Compared to infiltrating ductal carcinoma group，non-lactation mastitis group displayed regular shape，clear boundary，less speckle strong echo，no echo area，less hyperechoic halo，posterior echo enhancement，and less axillary nodes（P<0.05）. Infiltrating ductal carcinoma group and misdiagnosed group showed similar ultrasound features including irregular shape，unclear boundary，heterogeneous echo，and enriched blood supply，but displayed statistically significant of speckle strong echo（χ²=30.805，P<0.001），hyperechoic halo（χ²=20.282，P<0.001），and posterior echo enhancement （χ²=6.442，P=0.011）. Conclusions Non-lactation mastitis is easily misdiagnosed as infiltrating ductal carcinoma diagnosis by high-frequency color Doppler ultrasound. Attention to the observation of spotted strong echo，high echo halo，and rear echo enhancement are helpful for its correct diagnosis.
