390例乳腺肿块B超图像分析

本文总结了经手术病理证实的390例乳腺肿块的超声诊断结果,恶性肿块符合率为87.5％(111/127),良性肿块符合率83.3％(219/263),分析了主要声像特征。在声像图诊断中,肿块周围声晕不同程度的增厚是恶性肿块的重要特征,其声晕的厚薄与癌组织浸润早晚有关,浸润早期的菲薄声晕易误为良性肿块的完整包膜。良性肿块伴有其它病理改变时,易误诊为恶性肿块。

Study on Breast Neoplasm By B-ultrasound in 390 Cases

390 cases with breast neoplasm which had B-mode ultrasonograph and histopathology were studied. Vnanimous rates of B-mode ultra-sono graph and histopathology in malignant mass were 87.5%(111/127) and in benign mass were 83.3% (219/263) .Ultrasonographic feature d breast mass were studied. Breast carcinoma usually showed thick jagged echogenic border caused by tumor infiltration, which was relatire to the period of infiltration in carcinoma In the early period of infiltration, thin jagged border was easily confused with intact member of benign mass. When benign mass was companied by some changes of pathology, it sometimes was mistakenly thought as malignant mass.
