Abstract

Aim: To evaluate the ultrasonographic features of male breast nodules classified as Breast Imaging Reporting and Data System category 4.

Material and methods: A retrospective analysis of 79 breast nodules from 77 male patients, classified as Breast Imaging Reporting and Data System category 4 after ultrasonography, was conducted. The ultrasonographic features of benign and malignant nodules were evaluated and compared. Independent risk factors for malignancy were identified by logistic regression analysis. In addition, we conducted a subgroup analysis comparing the ultrasonographic features of gynecomastia and malignant nodules in male breasts.

Results: Differences were found in age of onset, calcifications, aspect ratio greater than 1/2, Adler grading of blood flow, and axillary lymph nodes. The presence of calcifications was an independent risk factor for malignancy in males. The results of the comparison between gynecomastia and breast cancer were essentially consistent with the former. However, the differences in calcifications were not as significant as those observed in the former.

Conclusions: We identified differences in age of onset, calcification, aspect ratio greater than 1/2, blood flow, and axillary lymph nodes between benign and malignant male breast nodules classified as Breast Imaging Reporting and Data System category 4, with calcification being an independent risk factor for malignancy. These features can help determine the nature of the nodules and guide biopsy decisions.

男性BI-RADS 4类乳腺病变的超声特征。
目的:探讨乳腺影像报告与资料系统第4类男性乳腺结节的超声特征。材料与方法:回顾性分析77例男性患者的79个乳腺结节,超声检查后归类为乳腺影像学报告与数据系统4类。对良、恶性结节的超声表现进行评价和比较。通过logistic回归分析确定恶性肿瘤的独立危险因素。此外,我们还对男性乳房发育不良和男性乳房恶性结节的超声特征进行了亚组分析。结果:两组在发病年龄、钙化、宽高比大于1/2、血流Adler分级、腋窝淋巴结等方面存在差异。钙化是男性恶性肿瘤的独立危险因素。男性乳房发育症与乳腺癌的比较结果与前者基本一致。然而,在钙化方面的差异并不像在前者中观察到的那样显著。结论:我们确定了男性乳腺良恶性结节的发病年龄、钙化、宽高比大于1/2、血流和腋窝淋巴结的差异,并将其归类为乳腺影像学报告和数据系统第4类,钙化是恶性肿瘤的独立危险因素。这些特征有助于确定结节的性质并指导活检的决定。
