【摘要】：目的探討CT及MRI在幕上腦實(shí)質(zhì)室管膜瘤中的表現(xiàn),旨在提高對(duì)幕上腦實(shí)質(zhì)室管膜瘤診斷的準(zhǔn)確率。方法回顧性分析我院2005年1月~2014年1月經(jīng)手術(shù)病理證實(shí)的16例幕上腦實(shí)質(zhì)內(nèi)室管膜瘤資料,12例行CT和MR檢查,3例單行CT檢查,1例單行MR檢查。結(jié)果僅2例為完全實(shí)性腫瘤,其余14例腫瘤表現(xiàn)為囊實(shí)性。其中6例囊變區(qū)以大囊表現(xiàn)為主,1例表現(xiàn)為單發(fā)大囊,余5例大囊周邊伴發(fā)小囊,由位于深部白質(zhì)區(qū)的大囊與位于靠近皮層區(qū)的小部分實(shí)質(zhì)構(gòu)成,以寬基底貼近大腦表面;余8例囊實(shí)性腫瘤以小囊表現(xiàn)為主,2例為單發(fā)偏心小囊變,余6例見(jiàn)多個(gè)囊變區(qū)。囊液的CT密度及MRI T2WI信號(hào)強(qiáng)度均高于同層面腦脊液。腫瘤實(shí)質(zhì)部分CT呈等、稍高密度,12例腫瘤實(shí)質(zhì)內(nèi)均見(jiàn)鈣化灶,增強(qiáng)掃描腫瘤實(shí)質(zhì)不均勻強(qiáng)化,囊壁及壁結(jié)節(jié)明顯強(qiáng)化。結(jié)論幕上腦實(shí)質(zhì)室管膜瘤CT和MR表現(xiàn)有一定特征,認(rèn)識(shí)這些特征有助于術(shù)前定性診斷。
[Abstract]:Objective to investigate the features of CT and MRI in ependymoma of supratentorial parenchyma in order to improve the diagnostic accuracy of supratentorial parenchymal ependymoma. Methods from January 2005 to January 2014, 16 cases of ependymoma in supratentorial parenchyma were retrospectively analyzed. CT and MR were performed in 12 cases, CT in 3 cases and MR in 1 case. Results only 2 cases were completely solid tumor, the other 14 cases showed cystic solid tumor. Among them, 6 cases had large cyst, 1 case had single large cyst, the other 5 cases had small cyst around the big cyst, which was composed of large cyst located in the deep white matter area and a small part of parenchyma near the cortical area, which was close to the surface of the brain with a wide base. The remaining 8 cases of cystic solid tumors were mainly small cystic lesions, 2 cases were single eccentric microcysts, and 6 cases had multiple cystic areas. The CT density and MRI T2WI signal intensity of cystic fluid were higher than that of cerebrospinal fluid at the same level. The CT of tumor parenchyma was isobaric and slightly high density. Calcification was found in 12 cases of tumor parenchyma. The enhancement of tumor parenchyma was not homogeneous and the cystic wall and wall nodules were obviously enhanced. Conclusion CT and MR features of supratentorial parenchymal ependymoma have some characteristics.
