目的探讨乳腺错构瘤超声声像图特征。方法回顾分析20例(22个肿块)女性乳腺错构瘤患者的超声及病理资料,总结声像图特点。结果肿块直径大小1.0~7.0 cm,平均直径4.26 cm。13个(59.1%)位于右乳,11个(50%)位于外上象限。肿瘤内部回声分为Ⅰ型、Ⅱ型和Ⅲ型。分别为Ⅰ型10个(45.4%),Ⅱ型4个(18.2%),Ⅲ型8个(36.4%)。19个(86.4%)为Adler 0级无血流供应,3个(13.6%)为AdlerⅠ级血流。结论乳腺错构瘤超声类似其他良性肿瘤表现,肿块内回声复杂多样,有一定的特征性。 Objective To investigate the ultrasonic sonographic features of hamartoma. Methods The ultrasound and pathological data of 20 cases (22 lumps) of female breast hamartoma were retrospectively analyzed, and the sonographic features were summarized. Results The diameter of the tumor was 1.0-7.0 cm and the average diameter was 4.26 cm. Thirteen (59.1%) were in the right breast and 11 (50%) were in the upper quadrant. Tumor internal echo is divided into type Ⅰ, type Ⅱ and type Ⅲ. They were type I 10 (45.4%), type II 4 (18.2%) and type III 8 (36.4%). Nineteen (86.4%) were Adler class 0 without blood flow supplies and 3 (13.6%) were Adler class I blood flow. Conclusions Ultrasound of breast hamartoma is similar to that of other benign tumors. The echoes in the tumor are complex and diverse, and have certain characteristics.
