乳腺非肿块型病变的超声临床分析

The Ultrasound Clinical Analysis of Breast Non-mass Lesions

目的:评价乳腺非肿块型病变的超声反应。方法:采用回顾性分析的形式对我院于2018年1月-2018年12月期间,所收治的经常规检查确诊的患者共50例予以分析。结果 :20例非肿块型乳腺病变反应中,恶性病变11例(55%),良性病变9例(45%)。其中3例为浸润性导管癌、4例为导管内癌、淋巴转移性低分化癌3例、纤维性腺癌1例、淋巴细胞性白血病2例、增生2例、腺病4例、炎性病变1例。20例非肿块型乳腺病变中,12例为片状低回声区域(60%),8例为微钙化片状低回声区域(40%);恶性组病灶最大直径为2.25±1.03(cm),良性组为3.09±1.02(cm),良性病变组微钙化比例77.8%和恶性病变27.3%;腋下异常淋巴结分析,良性病变9.1%,恶性病变55.5%。结论:非肿块型乳腺病变内部微钙化存在对导管内癌诊断具有显著价值。腋下存在淋巴结异常对于良恶性病变鉴别诊断有一定作用。

Objective: To evaluate the ultrasound reaction of breast non-mass lesions. Methods:Using retrospective analysis to analyze the total 50 patients who were diagnosed by routine examination from January 2018 to December 2018. Results: Among the 20 cases of non-mass breast lesions, 11 were malignant lesions(55%) and 9 were benign lesions(45%). Among them, 3 cases were invasive ductal carcinoma, 4 cases were intraductal carcinoma, 3 cases were lymphatic metastatic carcinoma, 1 case was fibrotic adenocarcinoma, 2 cases were lymphocytic leukemia, 2 cases were hyperplasia, 4 cases were adenopathy, and 1 case was inflammatory lesions. Among the 20 cases of non-mass breast lesions,12 cases were lamellar hypoacoustic region(60%)and 8 cases were microcalcified schistose hypoechoic region(40%). The maximum diameter of lesions in the malignant group was 2.25±1.03(cm), and that was 3.09±1.02(cm) in the benign group;the proportion of microcalcification in the benign group was77.8% and that in the malignant group was 27.3%. Abnormal axillary lymph node analysis, benign lesions was 9.1%, malignant lesions was 55.5%. Conclusion: The microcalcification in breast non-mass lesions has significant value in the diagnosis of intraductal carcinoma. The presence of axillary lymph node abnormality is useful in the differential diagnosis of benign and malignant lesions.
