【摘要】：目的比較子宮漿液性乳頭狀癌(UPSC)與子宮內(nèi)膜樣腺癌(EAC)的MRI檢查結(jié)果。方法回顧性分析經(jīng)手術(shù)病理證實(shí)的22例UPSC的MRI資料。隨機(jī)選擇同期收治、資料完整且經(jīng)手術(shù)病理證實(shí)的43例EAC的MRI資料作為對(duì)照。分析二者的MRI征象。結(jié)果 UPSC、EAC中腫塊型病灶分別為15(68.18%)、8(18.60%)例,二者比較,P0.05。UPSC和EAC在T2WI上病灶信號(hào)強(qiáng)度比較無統(tǒng)計(jì)學(xué)差異;在T1WI上4例UPSC病灶內(nèi)可見斑點(diǎn)狀高信號(hào)。22例UPSC中有14例(63.64%)宮腔內(nèi)病灶最大徑與最大肌層浸潤(rùn)深度的比值≤1,12例純型UPSC中10例(83.33%)其比值≤1,43例EAC中5例(11.63%)其比值≤1,三者比較,P均0.05。20例UPSC病灶周圍存在正常子宮內(nèi)膜(90.91%),12例純型UPSC病灶周圍均可見正常厚度子宮內(nèi)膜,10例(23.26%)EAC病灶周圍存在正常子宮內(nèi)膜,UPSC與EAC病灶周圍存在正常子宮內(nèi)膜率比較,P0.05。T1WI增強(qiáng)掃描中18例(81.82%)UPSC為明顯強(qiáng)化—上升型方式,明顯高于EAC(25.58%),P0.05。5例純型UPSC伴發(fā)卵巢腫塊,共8個(gè)卵巢腫塊的體積(≥50 mm)均大于其子宮病灶,8個(gè)卵巢腫塊中6個(gè)為巨大囊實(shí)性腫塊。純型UPSC中卵巢腫塊的出現(xiàn)率(41.67%)明顯高于EAC(6.98%),P0.05。結(jié)論 UPSC與EAC的MRI表現(xiàn)不同,UPSC以腫塊型病灶多見,病灶大小與肌層浸潤(rùn)深度不成比例,非病灶區(qū)多可見菲薄內(nèi)膜,血供較EAC豐富,增強(qiáng)掃描較EAC強(qiáng)化明顯,卵巢出現(xiàn)體積大于子宮病灶的巨大腫塊,囊實(shí)性多見。
[Abstract]:Objective to compare the MRI findings of serous papillary carcinoma (UPSC) and endometrial adenocarcinoma (EAC). Methods the MRI data of 22 cases of UPSC confirmed by operation and pathology were analyzed retrospectively. The MRI data of 43 cases of EAC confirmed by operation and pathology were randomly selected as control group. The MRI signs of both were analyzed. Results there were 15 (68.18%) and 8 (18.60%) mass lesions in UPSC,EAC. There was no significant difference in the signal intensity between P0.05.UPSC and EAC on T2WI. Dotted hyperintensity could be seen in 4 cases of UPSC on T1WI. Of 22 cases of UPSC, 14 cases (63.64%) had a ratio of maximum diameter to depth of myometrium infiltration 鈮，
