【摘要】：目的分析甲狀腺實性小結(jié)節(jié)(直徑10 mm)的超聲及病理學(xué)表現(xiàn),以提高超聲定性診斷水平。方法對照分析50例甲狀腺乳頭狀微小癌(papillary thyroid microcarcinoma,PTMC)和34例結(jié)節(jié)性甲狀腺腫(nodular goiter,NG)的聲像圖表現(xiàn),包括結(jié)節(jié)的位置、形態(tài)、大小、內(nèi)部及后方回聲、鈣化、邊界和血流情況,并與病理學(xué)表現(xiàn)相對照。結(jié)果PTMC多表現(xiàn)為低回聲結(jié)節(jié)(89.3%),縱橫比≥1(71.4%),伴有后方回聲衰減(64.2%),可見微小鈣化(37.5%);NG結(jié)節(jié)表現(xiàn)為中高回聲(64.7%),縱橫比1(73.5%),后方回聲無衰減(88.2%)。良惡性結(jié)節(jié)的回聲強度及后方回聲、縱橫比、微小鈣化、形態(tài)、邊界、血流阻力指數(shù)的差異有統(tǒng)計學(xué)意義。PTMC的病理基礎(chǔ)為不同比例組成的癌細(xì)胞和纖維間質(zhì)呈乳頭狀或濾泡狀結(jié)構(gòu)排列,可有纖維假包膜、砂粒體和腫瘤血管。NG的病理基礎(chǔ)為形態(tài)規(guī)則,邊界清晰,由大小不等濾泡結(jié)構(gòu)組成,伴薄層纖維組織包裹分隔濾泡組織,濾泡腔內(nèi)含多量膠質(zhì)。結(jié)論 PTMC和NG的病理構(gòu)成差異決定其超聲圖像特征的不同。
[Abstract]:Objective to analyze the ultrasonographic and pathological features of solid thyroid nodules (10 mm in diameter) in order to improve the qualitative diagnosis of thyroid nodules. Methods the sonographic features of 50 cases of papillary thyroid carcinoma (papillary thyroid microcarcinoma,PTMC) and 34 cases of nodular goiter (nodular goiter,NG) were analyzed, including location, shape, size, internal and posterior echo, calcification. Boundary and blood flow were compared with pathological findings. Results PTMC showed hypoechoic nodules (89.3%), aspect ratio 鈮，
