乳腺叶状肿瘤超声特征及与病理对照分析

A comparative analysis between ultrasonic characteristics of breast phyllodes tumor and its pathology

目的：研究乳腺叶状肿瘤的超声声像图特征,并与病理结果相对照,以期从超声角度提高对本病的认识。方法：分析经病理证实的16例乳腺叶状肿瘤的二维及彩色多普勒超声表现,并与病理结果对照分析。结果：二维图像肿块体积大小范围变化大,形态不规则可分叶,可有包膜,内部多为不均匀弱回声,可有液性暗区。CDFI良性血流0～Ⅰ级,恶性Ⅱ～Ⅲ级,阻力指数偏高。结论：乳腺叶状肿瘤的二维声像图具有一定特点,但无明显特异性,肿块的大小与良恶性之间无明显联系,结合肿块内部囊性变、彩色多普勒超声显示丰富的血流及高速高阻频谱,对提示恶性有意义。

Objective：TThis study was to investigate the ultrasonic imaging features of phyllodes tumors of breasts （PTB） comparing with their pathology and to know more about this disease.Methods：The grey scale images and color Doppler characteristics of sixteen patients with pathologically proved PTB were analyzed retrospectively. Results： The changing range of the tumors＇ volume was large while the shape was irregular. Lobulated shapes can he showed and peplos can he seen. The echoes inside were often weak and uneven. Fluidity free echoes in the middle of tumors can he found. Most of benign PTB showed that blood flow was grade 0 ～ Ⅰ while the malignant one was Ⅱ ～ Ⅲ. The resistant index （RI） was a little high showed by pulsed wave. Conclusion： The grey scale image of PTB has some characteristics. The characteristics have little obviously specificity. No manifest correlation has been found between the volume and the pathological features of tumors. The fluidity free echoes inside, rich flow, high peak systolic velocity （PSV） and high RI is useful to diagnose malignant mass.
