目的 研究乳腺分叶状肿瘤 (phyllode tumor of the breast,PTB)的超声表现 ,以期从超声角度提高对该病认识。方法 回顾性分析经手术病理证实 1 6例 PTB的超声表现。结果 1 6例 PTB中 5例为良性、 4例为交界性、 7例为恶性。所有病例按超声声像图不同表现分为三个类型 :5例表现为分叶不明显或浅分叶状的实质性肿块 ;6例表现为有明显分叶的实质性肿块 ;5例表现为囊实混合性肿块。肿瘤最大径≤ 5 .0 cm的 6例中 ,交界性及恶性共 5例 ;肿瘤最大径 >5 .0 cm的 1 0例中 ,良性者 4例。有 4例恶性 PTB表现为局部边界不清。恶性PTB的彩色多普勒血流分级多为 级和 级。结论 PTB具有一些特征性的超声声像图表现。超声对 PTB的诊断和鉴别诊断有重要的临床价值。肿块局部边界不清、血流丰富则提示恶性程度可能较高。良性 PTB也可表现为囊实混合性肿块。PTB的体积、分叶程度与良恶性之间无明显关系
Objective To study the ultrasound manifestations of phyllode tumor of the breast (PTB) in order to improve its understanding of the disease from the perspective of ultrasound. Methods The ultrasound findings of 16 cases of PTB confirmed by surgery and pathology were retrospectively analyzed. Results Of the 6 PTBs, 5 were benign, 4 were borderline, and 7 were malignant. All cases according to the different manifestations of ultrasound sonography is divided into three types: 5 cases manifested as unclear lobes of lobectomy or substantive mass; 6 cases showed significant lobulation of the substantive mass; 5 cases showed Capsule mixed mass. Among the 6 cases whose tumor diameter was less than 5.0 cm, there were 5 cases of borderline and malignancy; 4 cases of benign cases were found in 10 cases whose tumor diameter was> 0.5 cm. Four cases of malignant PTB showed unclear boundary. Malignant PTB color Doppler flow grading mostly level and level. Conclusion PTB has some characteristic ultrasonography. Ultrasound has important clinical value in the diagnosis and differential diagnosis of PTB. Local lumps unclear, rich in blood flow may suggest that the degree of malignancy may be higher. Benign PTB can also be expressed as cystic solid mixed mass. There was no significant relationship between the volume of PTB, degree of lobulation and benign or malignant
