不同肿块类型MDE与IDC,DCIS的彩超影像分析

目的分析不同肿块类型乳腺导管扩张症(MDE)与浸润性导管癌(IDC)、导管原位癌(DCIS)在彩色多普勒超声(CDFI)下的影像表现。方法回顾性分析我院2017年4月至2019年3月收治的经病理证实为MDE的62例患者的临床资料进行研究(MDE组)。另分析同期经病理证实为乳腺癌患者95例的临床资料,其中IDC51例(IDC组),DCIS44例(DCIS组)。分析受试者术前彩色多普勒超声(CDFI)图像,比较三组的临床资料、肿块型病灶及导管型病灶影像学特征。结果MDE组的发病年龄明显低于IDC组、DCIS组(均P<0.05),MDE组位于外周的病灶明显少于IDC组、DCIS组(均P<0.05),MDE组更多病灶位于中央,此外MDE组囊实性及囊性肿块所占比例明显高于IDC组、DCIS组(均P<0.05);肿块型MDE组病灶最大径明显小于DCIS组(P<0.05),形态规则、边缘完整的肿块型病灶明显高于IDC组、DCIS组(均P<0.05),有强回声点、周边高回声晕、后方回声衰减的特征明显低于IDC组、DCIS组(均P<0.05),且0~Ⅰ级Adler血流血流检出率明显高于IDC组、DCIS组(均P<0.05),此外肿块型MDE病灶伴内部液性无回声区较IDC、DCIS多见(均P<0.05);导管型MDE有强回声点的特征明显低于DCIS组(均P<0.05),其余各项差异均无统计学意义(均P>0.05)。结论CDFI下MDE病灶多表现为肿块型,以囊实性或囊性肿块居多,与IDC、DCIS在CDFI下特征表现区别较大,对MDE的诊断及其与乳腺癌IDC、DCIS的鉴别诊断具有重要价值。

Image Performance Analysis of Different Tumor Types MDE and IDC and DCIS under Color Doppler Ultrasound

Objective To analyze the imaging manifestations of different tumor types MDE,IDC and DCIS under color Doppler ultrasound.Method The clinical data of 62 patients with pathologically confirmed MDE admitted to our hospital from April 2017 to March 2019 were retrospectively analyzed(MDE group).In addition,clinical data of 95 cases of breast cancer confirmed by pathology during the same period were analyzed,including IDC51 cases(IDC group)and DCIS44 cases(DCIS group).The preoperative color Doppler ultrasound(CDFI)images of the subjects were analyzed,and the clinical data,tumor lesions and ductal lesions imaging characteristics of the three groups were compared.Results The age of onset in the MDE group was significantly lower than that of the IDC group and THE DCIS group(all P<0.05),the number of lesions in the peripheral zone of the MDE group was significantly lower than that of the IDC group and the DCIS group(all P<0.05),and more lesions were located in the center of the MDE group.In addition,the proportion of cysts and cystic masses in the MDE group was significantly higher than that of the IDC group and the DCIS group(all P<0.05);Type mass lesions maximum diameter MDE approach based group was obviously less than DCIS group(P<0.05),type edge shape rules,the complete mass lesions significantly higher than that of IDC,DCIS group(all P<0.05),there are strong points of the echo,peripheral hyperechoic halo,rear echo attenuation characteristics of significantly lower than that of IDC,DCIS group(all P<0.05),and the level 0~ⅠAdler blood flow was much higher than that of IDC,DCIS group(all P<0.05),and mass type MDE approach based lesions associated with internal liquidity anechoic area from IDC,DCIS see more(all P<0.05);The duct-type MDE with strong echogenicity was significantly lower than that of the DCIS group(all P<0.05),and the other differences were not statistically significant(all P>0.05).Conclusion Most of the MDE lesions under CDFI are tumor types,mostly cystic and solid or cystic masses,which are significantly different from THE characteristic manifestations of IDC and DCIS under CDFI,and have important value in the diagnosis of MDE and its differential diagnosis with IDC and DCIS of breast cancer.
