乳腺管状腺瘤的超声图像特征分析

Ultrasonographic features of breast tubular adenoma

目的:分析乳腺管状腺瘤的超声图像特点,总结用于鉴别诊断管状腺瘤的特征性表现。方法:回顾性分析33例乳腺管状腺瘤的超声图像、病理及临床资料,归纳总结乳腺管状腺瘤的超声图像特征。结果:28例(84.8%)乳腺管状腺瘤表现为BI-RADS超声分类3类结节的典型图像特征。主要超声表现包括:结节边缘光整(28/33,84.8%)、椭圆形(29/33,87.9%)、椭圆形伴分叶状改变(9/33,27.3%)、平行生长(33/33,100%)、低回声(31/33,93.9%)、内部回声不均匀伴条索状高回声(20/33,60.6%)、结节周边及内部可见血流信号(18/33,54.5%)。结节周围组织回声无改变,腋窝均未见异常肿大的淋巴结。结论:乳腺管状腺瘤超声图像符合BI-RADS分类良性病变特征,结节内部回声不均匀伴条索状高回声和椭圆形伴分叶状的征象与病理改变相关,对鉴别诊断乳腺管状腺瘤有一定的提示作用,分析这些图像细节有助于提高术前诊断率。

Objective:To analyze the ultrasonographic features of tubular adenoma of breast and to summarize the characteristic images.Methods:The ultrasonographic,pathological and clinical data of 33 cases of tubular adenoma of breast were analyzed retrospectively.The ultrasonographic features of tubular adenoma of breast were summarized.Results:Twenty-eight cases(84.8%)of tubular adenoma of breast showed typical image features of category 3 in BI-RADS ultrasonography.Main ultrasonographic features included nodules with circumscribed margins(28/33,84.8%),elliptic nodules(29/33,87.9%),elliptic nodules with lobulated changes(9/33,27.3%),parallel orientation(33/33,100%),internal hypoechoes(31/33,93.9%),and homogeneous internal echoes with cords-like hyperechoes(20/33,60.6%).Blood flow signals were detected in 18 nodules(18/33,54.5%).There were no echoic changes in the tissue around the nodules,and no abnormal enlarged lymph nodes were found in axilla.Conclusion:The ultrasound images of breast tubular adenoma had the characteristics of BI-RADS classification of benign lesions.The signs of cords-like internal hyperechoes and lobed margin were related to pathological changes.It is helpful for differential diagnosis of tubular adenoma of breast.Analysis of image details is helpful to improve the preoperative diagnosis rate.
