| Summary: | Ductal abnormalities, such as dilated ducts with intraductal lesions, are frequently the primary ultrasound findings prompting biopsy and resulting in the early diagnosis of breast cancer or high-risk lesions. However, the Breast Imaging Reporting and Data System (BI-RADS) ultrasound lexicon provides limited guidance on these findings, categorizing them merely as associated features. To address this limitation, this review presents a critical analysis of existing literature and proposes a new classification encompassing three distinct subtypes: dilated ducts alone, dilated ducts with intraductal echoes, and intraductal masses. Additionally, an interpretation algorithm is introduced that incorporates lesion size and suspicious ultrasound features to guide BI-RADS assessment. This structured approach aims to standardize terminology, improve diagnostic accuracy, and promote consistent management of ductal abnormalities, especially in asymptomatic women. |
