To describe the ultrasonographic (US) features of adenoma in a lactating breast.
The US scans of 11 lactating adenomas in nine patients aged 25-36 years examined in 1991-1996 were retrospectively reviewed. In all lesions, diagnoses were cytologically or histologically proved after US-guided fine-needle aspiration biopsy (eight lesions) or core biopsy (three lesions). Six patients were lactating, and three patients were in the third trimester of pregnancy. The US features analyzed were shape, orientation to the chest wall, border characteristics, echogenicity, homogeneity, enhancement or shadowing, and depth within the breast.
Most lesions had benign US features such as ovoid shape with the long axis parallel to the chest wall (10 of 11), well-defined margins (eight of 11), homogeneous echotexture (eight of 11), and posterior acoustic enhancement (10 of 11). Four lesions had US features that resembled malignant lesions, such as irregular margins, heterogeneous echotexture, and posterior acoustic shadowing.
The US features, although generally benign, are not specific. Tissue sampling with fine-needle aspiration biopsy is recommended. Core biopsy is necessary if a diagnosis cannot be made with the aspirate but is not performed initially because of the possibility of milk fistula formation.
描述哺乳期乳腺腺瘤的超声（US）特征。
回顾性分析1991年至1996年间对9例年龄在25 - 36岁患者的11个哺乳期腺瘤进行的超声扫描。所有病变均在超声引导下经细针穿刺活检（8个病变）或粗针活检（3个病变）后经细胞学或组织学证实。6例患者处于哺乳期，3例患者处于妊娠晚期。分析的超声特征包括形状、与胸壁的方位关系、边界特征、回声性、均匀性、增强或声影以及在乳腺内的深度。
大多数病变具有良性超声特征，如长轴与胸壁平行的椭圆形（11个中的10个）、边界清晰（11个中的8个）、回声质地均匀（11个中的8个）以及后方回声增强（11个中的10个）。4个病变具有类似恶性病变的超声特征，如边界不规则、回声质地不均匀以及后方声影。
超声特征虽一般为良性，但不具有特异性。建议采用细针穿刺活检进行组织采样。如果抽吸活检无法做出诊断，但因有形成乳瘘的可能性而最初未进行粗针活检，则粗针活检是必要的。
