【摘要】：目的比较子宫浆液性乳头状癌(UPSC)与子宫内膜样腺癌(EAC)的MRI检查结果。方法回顾性分析经手术病理证实的22例UPSC的MRI资料。随机选择同期收治、资料完整且经手术病理证实的43例EAC的MRI资料作为对照。分析二者的MRI征象。结果 UPSC、EAC中肿块型病灶分别为15(68.18%)、8(18.60%)例,二者比较,P0.05。UPSC和EAC在T2WI上病灶信号强度比较无统计学差异;在T1WI上4例UPSC病灶内可见斑点状高信号。22例UPSC中有14例(63.64%)宫腔内病灶最大径与最大肌层浸润深度的比值≤1,12例纯型UPSC中10例(83.33%)其比值≤1,43例EAC中5例(11.63%)其比值≤1,三者比较,P均0.05。20例UPSC病灶周围存在正常子宫内膜(90.91%),12例纯型UPSC病灶周围均可见正常厚度子宫内膜,10例(23.26%)EAC病灶周围存在正常子宫内膜,UPSC与EAC病灶周围存在正常子宫内膜率比较,P0.05。T1WI增强扫描中18例(81.82%)UPSC为明显强化—上升型方式,明显高于EAC(25.58%),P0.05。5例纯型UPSC伴发卵巢肿块,共8个卵巢肿块的体积(≥50 mm)均大于其子宫病灶,8个卵巢肿块中6个为巨大囊实性肿块。纯型UPSC中卵巢肿块的出现率(41.67%)明显高于EAC(6.98%),P0.05。结论 UPSC与EAC的MRI表现不同,UPSC以肿块型病灶多见,病灶大小与肌层浸润深度不成比例,非病灶区多可见菲薄内膜,血供较EAC丰富,增强扫描较EAC强化明显,卵巢出现体积大于子宫病灶的巨大肿块,囊实性多见。
[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，
