Bloody nipple discharge in infancy and childhood is extremely rare, and mammary duct ectasia is the most common etiology. Ultrasound (US) findings of mammary duct ectasia include dilated ducts and tubular anechoic lesions that may contain echogenic debris in the subareolar region. However, mammary duct ectasia may show variable US findings, which are not well described in the literature. We report 3 cases of mammary duct ectasia in infancy and childhood with variable imaging findings, including complex cystic and solid lesions. Detailed initial clinical and US findings and serial follow-up US images are described.
婴儿和儿童的血性乳头溢液极为罕见，而乳腺导管扩张症是最常见的病因。乳腺导管扩张症的超声（US）表现包括扩张的导管和管状无回声病变，在乳晕下区域可能含有回声性碎屑。然而，乳腺导管扩张症的 US 表现可能具有多种变化，文献中对此描述得还不够详细。我们报告了 3 例婴儿和儿童的乳腺导管扩张症，其影像学表现具有多样性，包括复杂的囊性和实性病变。详细描述了初始的临床和 US 表现以及连续的随访 US 图像。
