The sonographic features of 22 patients with histologically benign intraductal papillomas are presented, with clinical, mammographic, galactographic, and histopathologic correlation. The most common presenting feature in this series is a palpable central breast mass in an elderly woman. Sonography was abnormal in all 22 patients. The typical sonographic features include a well-defined, smooth-walled, solid, hypoechoic nodule or a lobulated, smooth-walled, cystic lesion with solid components. Dilated ducts are a common feature, often with visible solid intraluminal echoes. These findings suggest the diagnosis of an intraductal papilloma. The differential diagnosis includes fibroadenoma and phyllodes tumor (for large solid lesions) and intracystic carcinoma (for complex cystic lesions). Mammograms are frequently normal (36% of patients). When abnormal, the mammographic features are of a smooth-walled, well-defined mass or increased retroareolar opacity. Contrary to the reported literature, calcification was seen infrequently. We conclude that ultrasonography is useful in the detection and delineation of intraductal papillomas.

介绍了22例组织学上良性导管内乳头状瘤患者的超声特征,并与临床,乳房X线照片,乳腺摄影和组织病理学相关。该系列最常见的表现是一名老年妇女的中央乳腺肿块。所有22例患者的超声检查均异常。典型的超声特征包括界限分明,光滑的壁,实体的低回声结节或具有固体成分的小叶的光滑壁的囊性病变。扩张的导管是常见特征,通常伴有可见的固体腔内回声。这些发现提示导管内乳头状瘤的诊断。鉴别诊断包括纤维腺瘤和叶状肿瘤(对于大的实体病变)和囊内癌(对于复杂的囊性病变)。乳房X线照片通常是正常的(36%的患者)。异常时,乳房X光检查的特征是壁光滑,边界清晰或乳晕后不透明性增加。与报道的文献相反,很少见到钙化。我们得出的结论是,超声检查可用于导管内乳头状瘤的检测和勾画。
