Objective To analyze the relationship of breast cystic lesions with pathology and to recommend appropriate man -agement for these lesions .Methods From December 2005 to December 2010 , 135 consecutive pathologically proven or long time followed cystic lesions were studied retrospectively .US features of lesions were classified into 5 types,and positive values (PPVs) were calculated for each type .BI-RADS classification was used at ultrasonography and mammography .We analyzed the correlation between these factors.Results In ultrasonography, typeⅠwas 39(28.9%), typeⅡ46 (34.1%), typeⅢ13 (9.6%), typeⅣ14 (10.4%), and typeⅤ23(17.0%).The positive prognostic value for malignant in typeⅠwas 0%, typeⅡ was 2.2%, typeⅢwas 30.8%, typeⅣwas 50%, and typeⅤwas 56.5%.There was statistically significant ( P =0.000).The different between ultrasonography and mammography BI-RADS classification was statistically significant ( P =0.000).Conclusion There is different between the diagnosis of breast cystic lesions by US and mammography with BI -RADS classification .Using both of two methods can help radiologist to determine management recommendations in clinic working .%目的 通过分析乳腺囊性肿块病变超声及钼靶表现并与病理对照,为临床提出进一步处理意见. 方法 回顾性分析乳腺囊性病变患者112例,共135个病灶. 根据病灶内部囊性、实性成分比例和分布特点将其分为5型,计算每一类型恶性病灶阳性预测值,对这些病灶的良恶性行超声及X线摄影技术BI-RADS分级,分析相关性. 结果 超声分型中Ⅰ型39个(28.9%),Ⅱ型46个(34.1%),Ⅲ型13个(9.6%),Ⅳ型14个(10.4%),Ⅴ型23个(17.0%),阳性预测值分别为0、2.2%、30.8%、50.0%和56.5%,且各类型间阳性预测值有显著性差异, P =0.000,Ⅲ、Ⅳ、Ⅴ型阳性预测值明显高于Ⅰ型和Ⅱ型. 超声和X线摄影技术BI-RADS分级之间具有显著性差异. 结论 超声与X线摄影技术BI-AIDS分级在诊断乳腺囊性病变中存在差异,联合应用有助于提高符合率.
