乳腺导管内癌的彩超诊断及误诊分析(一)
详细内容
【摘要】 〔目的〕 探讨彩超对乳腺导管内癌的诊断及鉴别诊断价值。〔方法〕回顾性分析经手术病理证实的20例乳腺导管内癌彩超声像图。〔结果〕根据20例乳腺导管内癌声像图可分为3种类型:Ⅰ无明显边界的局限性乳腺回声改变。Ⅱ乳腺内边界尚清的团块。Ⅲ乳腺导管扩张伴导管壁增厚。〔结论〕彩超诊断乳腺导管内癌应结合临床表现及其他检查手段综合分析。

Abstract: 〔Objective〕To eva luate the value of color doppler ultrasound in the diagnosis and differential diagnosis of ductal carcinoma in situ of the breast. 〔Methods〕20 patients with ductal carcinoma in situ confirmed by pathological results were retrospectively analysed with color doppler ultrasound imaging. 〔Results〕 The echoic imaging of ductal carcinoma in situ was classified into three types: type 1,echo changes in local breast issue without obvious contour;type 2, crumb with obvious contour in breast;type 3,ductal dilation with thick ductal wall. 〔Conclusion〕In the diagnosis of ductal carcinoma in situ with color doppler ultrasound,it is necessary to bine with clinical manifestations and other examination.

乳腺导管内癌(DCIS)是来源于乳腺导管系统的非浸润性乳腺癌,早发现早治疗对预后有重大意义。超声作为一种无创可重复性的检查手段有助于DCIS的诊断。
1 资料与方法
1.1 临床资料
2004年8月至2010年1月我院收治的20例患者,均经手术和病理结果证实为乳腺导管内癌,年龄34~77岁,平均57岁,其中女性19例,男性1例。
1.2 方法
采用ATL HDI5000,SEQUOIA 512及Philips IU22彩色超声诊断仪,线阵探头,探头频率5?12MHz,选用仪器的乳腺预设条件,嘱患者充分暴露双侧乳房,取仰卧位,采用直接探测法,以乳头为中心作扇形扫查和放射状扫查,以求完整地扫查整个乳腺,发现异常区域或肿块做重点扫查,记录其边界、形态、大小等,同时扫查双侧腋窝观察有无肿大淋巴结。
