目的 :探讨超声对乳腺导管内乳头状肿瘤的诊断与鉴别诊断价值。方法 :观察分析 31例经病理证实的导管内乳头状肿瘤的声像图表现 ,对其中 5例导管内乳头状癌着重阐述 ,并加以鉴别。结果 :导管内乳头状肿瘤声像图大体分四型 :导管扩张型、导管囊状扩张型、导管无扩张型及多发肿瘤型。导管内乳头状癌具有形态边缘不规则、回声不均质伴钙化、宽基底邻近管壁有增厚及血供丰富等特点。结论 :超声对乳腺导管内乳头状肿瘤的定性及定位诊断价值较大 ,且对鉴别乳头状瘤与乳头状癌有一定价值
Objective: To investigate the value of ultrasound in the diagnosis and differential diagnosis of intraductal papillary tumors. Methods: The sonographic findings of 31 cases of pathologically confirmed intraductal papillary tumors were observed and analyzed. Five cases of intraductal papillary carcinoma were emphatically described and identified. Results: Intraductal papillary tumor sonogram roughly divided into four types: catheter dilatation, duct dilatation, duct dilatation and multiple tumor type. Intraductal papillary carcinoma with irregular edge morphology, echo heterogeneity with calcification, wide base adjacent to the wall thickening and blood supply and other characteristics. Conclusion: The diagnosis of intraductal papillary tumors by ultrasound is of great value in the diagnosis and diagnosis of papilloma and papillary carcinoma
