摘　　要：目的探讨超声对导管型乳腺癌与乳腺导管内乳头状瘤(IDP)的鉴别诊断意义,研究导管型乳腺癌的超声表现特征。方法对超声表现为导管增粗或扩张并经手术病理证实的31例乳腺癌与30例IDP病灶进行回顾性对照分析。结果导管型乳腺癌与IDP在导管形态、走行、管壁回声、钙化灶等方面差异均有统计学意义(P<0.05)。导管型乳腺癌22例(70.97%)可探及血流信号,与IDP血流显示率(70.00%)比较差异无统计学意义,但导管型乳腺癌血流沿导管周边分布,而IDP血流多分布于导管腔内实体内部,两者血流的分布不同,差异有统计学意义(P<0.05)。结论超声对导管型乳腺癌与IDP的鉴别诊断具有重要价值;导管增粗、走行僵硬、沿导管分布的微小钙化灶和导管周边丰富的血流信号是导管型乳腺癌的超声表现特征。Objective To explore the significance of ultrasound differential diagnosis in ductal type breast cancer and breast intraductal papilloma（IDP）, and study the ultrasound characteristics of ductal type breast cancer. Methods The ultrasonic features of 31 breast cancer patients with thickened or dilated duct and 30 IDP patients confirmed by pathology were retrospectively studied and compared. Results There were significant differences of appearance, course, echo texture of duct wall and microcalcification between the two lesions （P〈0.05）. The difference of detection rates of blood flow signals was not significant between ductal type breast cancer （70.97%） and IDP （70.00%）. But the blood flow signals were often detected in the surrounding of duct in ductal type breast cancer, while solid region inside the duct in IDP （P〈0.05）. Conclusion Ultrasound has important value in differential diagnosis of ductal type breast cancer and IDP. Ultrasound characteristics of duetal type breast cancer often show duct thickening, stiff and irregular course,microcalcification along with the duct and abundant blood flow signals surrounding the duct.
