乳腺纤维腺瘤声像图及彩色多普勒血流特征与病理对照分析

目的　对乳腺纤维腺瘤的高频声像图及彩色多普勒血流的表现进行探讨 ,并与病理对照分析。方法　对 3 6例经手术、病理证实的乳腺纤维腺瘤的高频声像图及彩色多普勒血流进行了回顾性分析。结果　典型乳腺纤维腺瘤表现为 :形态规则 ,椭圆形或圆形 ,纵横径比值 <0 .8,边界清晰 ,有完整包膜 ,内部回声均匀 ,后方回声增强。非典型乳腺纤维腺瘤表现为 :形态不规则 ,内部回声不均匀 ,可见粗钙化 ;部分肿块呈结节状或分叶状融合。彩色多普勒血流测及RI <0 .8。结论　高频声像图特征及彩色多普勒血流表现为超声诊断乳腺纤维腺瘤提供了重要依据

High Frequency Ultrasonography and Color Doppler Flow Imaging of Breast Fibroadenoma Compared with Pathology

Objective To assess the characteristics of high frequency ultrasonography (HFP) and color Doppler flow imaging (CDFI) for breast fibroadenoma. Methods HFU and CDFI were reviewed and compared with pathological results in 36 cases of breast fibroadenoma. Results The typical findings of breast fibroadenoma were with regular elliptical or round shapes, transverse-longitudinal axis ratio less than 0.8, clear boundary, a fine smooth edge of capsule, regular inside echoes and rear echo enhancement. The non-typical findings of breast fibroadenoma were irregular shape, and inhomogenous internal echoes and sometimes with coarse calcification or micro-calcification. Some masses appeared to be nodular or lobular. The resistant index (RI) was less than 0.7 in CDFI. Conclusion The features of high frequency ultrasonography and CDFI could be used as an important reference for diagnosis of breast fibroadenoma.
