To determine the importance of a dilated duct pattern at mammography.
Mammograms obtained in 46 women with histopathologically proved, asymmetrically dilated ducts were retrospectively studied. The laterality and location of the asymmetrically dilated duct, the presence of branching, and associated findings such as microcalcifications, nipple discharge, and interval change were evaluated.
Eleven patients (24%) had malignant results (ductal carcinoma in situ or invasive ductal carcinoma). Among these, six (54%) had suspicious microcalcifications. Nonsubareolar location and interval change are significant (P = .04) variables associated with malignancy.
Mammographic asymmetrically dilated ducts in a nonsubareolar area that are associated with interval change, suspicious microcalcifications, or both warrant biopsy.
确定乳腺钼靶检查中扩张导管模式的重要性。
对46例经组织病理学证实存在不对称扩张导管的女性的乳腺钼靶图像进行回顾性研究。评估不对称扩张导管的侧别和位置、分支情况以及相关表现，如微钙化、乳头溢液和间期变化。
11例患者（24%）结果为恶性（导管原位癌或浸润性导管癌）。其中，6例（54%）有可疑微钙化。乳晕外位置和间期变化是与恶性肿瘤相关的显著（P = .04）变量。
乳腺钼靶检查中，乳晕外区域出现与间期变化、可疑微钙化或两者相关的不对称扩张导管，值得进行活检。
