高频超声在乳腺乳头腺瘤中的诊断价值

The diagnosis value of high-frequencyy ultrasound in nipple adenoma

目的:探讨高频超声在乳腺乳头腺瘤(NA)中的诊断价值。方法:回顾性分析2012年1月-2022年12月我院55例经病理确诊为乳腺NA的术前超声表现,观察病变部位、内部回声、形态、边界、血流信号、与周边的毗邻关系,以及有无伴随其他乳腺病变。结果:NA超声表现呈现多样化,超声声像图分为:①结节型18例(32.7%):乳头内或乳头根部结节,结节直径3.7~22mm,实性低回声17例,囊实性1例,边界清,椭圆形,血流不丰富;②乳头肿大型16例(29.1%):乳头肿大、回声减低伴丰富血流;③中央导管扩张型7例(12.7%):中央区导管扩张,内径约2.0~4.5mm;④无特殊表现型14例(25.5%)。单纯NA组36例,NA伴良性病变组14例,NA伴恶性病变组5例。NA伴恶性病变组年龄>50岁(60%)明显多于单纯NA组(16.7%),差异具有统计学意义(P=0.028)。结论:NA可单独发生,也可与良性病变或恶性病变伴发,高频超声可显示NA的典型声像图特征,为临床诊疗提供影像学支持。

Objective:To investigate the diagnostic value of high-frequency ultrasound in nipple adenoma(NA).Methods:The preoperative ultrasonographic findings of 55 patients pathologically confirmed NA in the First Affiliated Hospital of Zhengzhou University from January 2012 to December 2022 were retrospectively analyzed.The location,internal echo,mor-phology,boundary,blood flow signal,the neighborhood relationship between the lesion and the surrounding area and whether there were any accompanying breast lesions.Results:The ultrasonic manifestations of NA were diversified.The ultrasound im-ages were divided into four types:①nodular type,18 cases(32.7%),nodular mass in the nipple or at the root of the nipple,oval shaped,well-demarcated,17 cases were solid hypoechoic and the other was cystic solid one.The diameter of the nodule was 3.7~22 mm,and the color Doppler flow showed not rich blood flow;②swollen nipple type,16 cases(29.1%),swollen nip-ple,echo reduction and abundant blood flow signals;③dilation of the central duct type,7 cases(12.7%)with a width of ap-proximately 2.0~4.5 mm with good internal sound transmission;④no special phenotype,14 cases(25.5%)showed no special ul-trasonic findings.There were 36 cases in the simple NA group,14 cases in NA combined with benign lesions group and 5 cases in the NA combined with malignant lesions group.Over 50-year-old(60%)in the NA combined with malignant lesions group was significantly higher than that of the simple NA group(16.7%),and the difference was statistically significant(P-0.028).Conclusion:NA can occur alone or coexist with benign or malignant lesions.The sonographic characteristics of NA were displayed via ultrasound,providing imaging support for clinical diagnosis and treatment.
