乳腺导管内癌的X线、病理与BI-RADS分级特点

Mammography, pathology and BI-RADS categorization in breast ductal carcinoma in situ

目的探讨乳腺导管内癌(DCIS)的x线特点与BI-RADS分级的应用价值。方法收集30例病理证实的DCIS病例,回顾性分析其X线与病理特点,分析BI-RADS分级的分布与阳性预测值。结果 DCISX线以钙化为主,14例(46.7%),形态为泥沙样、分枝状及多形性钙化;单纯肿块3例(10.0%);结构扭曲征象2例;无特殊改变(即阴性)11例。BI-RADS:0级8例,2级2例,3级2例,4级9例,5级9例,BI-RADS阳性预测值60.0%。结论 DCIS的X线表现为单纯钙化为主,BI-RADS分级阳性预测值较低,需其他检查方法弥补。

Objective To explore the mammographic features and value of breast imaging reporting and data system （BI-RADS） in ductal carcinoma-in-situ （DCIS）. Methods The mammography, positive predictive value of BI-RADS categorization, and pathology of DCIS in 30 pa- tients were retrospectively analyzed. Results Microcalciflcation was the dominant feature in DCIS and was sand-like, branching or pleomorphic （14 cases）. Other features included mass （3） and architectural distortion （2）. Mammography was normal in 11 patients. BI-RADS categories were 0 （8 cases）, 2 （2 cases）, 3 （2 cases）, 4 （9 eases） and 5 （9 cases） with positive predictive value of 60.0%. Conclusion The dominant mammogram feature of DCIS is microcalcification. The positive predictive value of BI-RADS categorization is low and should be complemented by other investigations.
