乳腺导管内癌的超声诊断及误诊分析

Ultrasonic Diagnosis of Breast Ductal Carcinoma in Situ and the Analysis on Misdiagnosis

目的:探讨乳腺导管内癌的超声表现及误诊原因。方法:回顾分析经手术病理证实的17例乳腺导管内癌的超声声像图特征。结果:17例病灶中,超声诊断恶性肿瘤14例,良性病变2例,1例未发现肿块;超声诊断符合率为82.3%。根据文献和本研究中病灶的声像图特征,将17例病变分为5类:实性肿块型(6例),导管扩张型(5例),结构紊乱型(4例),囊性病灶型(1例),其他类型(1例)。结论:乳腺导管内癌的超声表现多样,充分认识乳腺导管内癌的超声声像图特征可减少误诊,结合钼靶及乳腺导管内镜检查可以减少漏诊。

Objective：To investigate the ultrasonographic findings of breast ductal carcinoma in situ and the causes of misdiag-nosis .Methods ：Ultrasonographic features of 17 cases with breast ductal carcinoma in situ which were confirmed by operation and pathology were retrospectively reviewed .Results：Among the 17 cases of lesions ,according to the ultrasonic diagnosis there were 14 cases of malignant tumor ,2 cases of benign lesions ,and 1 case with no mass .Diagnostic coincidence rate was 82 . 3% by ultrasound .According to the characteristics from literatures and lesions in this study ,17 cases of lesions were roughly classified into 5 categories ：solid mass（6 cases） ,conduit ectasia（5 cases） ,architecture disorder（4 cases） ,cystic mass（1 case） , other type（1 case） .Conclusions ：The ultrasonographic findings of breast ductal carcinoma in situ are varied .Fully understand-ing the ultrasonographic features of breast ductal carcinoma in situ which can decrease missed-diagnosis ,combined with mam-mography examination and breast duct endoscopy which can reduce misdiagnosis ,will improve the diagnostic coincidence rate .
