The Breast Imaging Reporting and Data System (BI-RADS) standards have limitations regarding classifying and managing central intra-ductal papillary masses. Changes to the standards are necessary to provide early and effective treatment. To summarize the ultrasonographic imaging features of central mammary ductal papillary masses, this retrospective study included 56 participants. In identifying benign versus malignant lesions, the most significant indicators were angular edges and the long diameter of the tumor parallel to the duct. In the comparison of diagnostic efficacy for central mammary ductal tumors, the post-operative pathologic malignant upgrade rate of BI-RADS was 33.3%, and that of the new standard criteria was 14.2%. The angle of the wall of the tumor relative to the duct was most helpful. When BI-RADS is used to evaluate a papillary mass in a central duct, it is more accurate when the tumor is parallel to the duct than parallel to the skin.

乳腺影像报告和数据系统 (BI-RADS) 标准在分类和管理中央导管内乳头状肿块方面存在局限性。为了提供早期和有效的治疗，必须改变标准。为了总结中央乳腺导管乳头状肿块的超声成像特征，这项回顾性研究包括 56 名参与者。在鉴别良恶性病变时，最重要的指标是棱角和肿瘤平行于导管的长径。在中央乳腺导管肿瘤诊断疗效对比中，BI-RADS术后病理恶性升级率为33.3%，新标准为14.2%。肿瘤壁相对于导管的角度最有帮助。
