摘要
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。
Objective To study the ultrasonic characteristics of the breast phyllode tumor(PTB)for enhancing the knowledge of the disease.Methods The ultrasonography of 16 patients with pathologically proved PTB were analyzed retrospectively.Results Of all cases,5 cases were benign PTB,4 cases were borderline and 7 cases were malignant PTB The ultrasonic characteristics of images were divided into three types In 6 cases whose longest diameter of the tumor was≤5 0 cm,5 cases were malignant and borderline PTB.In 10 cases with the longest diameter of the tumor more than 5 0 cm,benign PTB was seen in 4 cases.Four malignant cases revealed part of tumor margin unclear.Most of malignant PTB showed blood flow grade Ⅱ～Ⅲ.Conclusions Several characteristic features were found in the ultrasound images Ultrasonography is of great value in diagnosis and differential diagnosis of PTB Unclear margin of the tumor and rich blood flow signals may indicate malignancy Benign PTB can also be expressed as mixed echoes of cystic and solid Size of the tumor and phyllode extent are not seen to be related to its pathological classification
