【摘要】：目的探討MRI對(duì)顱內(nèi)腦膜瘤的臨床診斷價(jià)值。方法回顧性分析我院2014年1月-2015年12月期間接收并經(jīng)手術(shù)病理確診的96例腦膜瘤患者的MRI檢查資料,并對(duì)腦膜瘤患者的病變大小、位置、形態(tài)等MRI影像特征、檢出率及其病理特點(diǎn)進(jìn)行綜合分析。結(jié)果 96例腦膜瘤患者均為單發(fā)腫瘤,其中腫瘤位于頂部大腦凸面、前顱底、中顱凹底、后顱底、大腦鐮旁的患者分別有39例、23例、18例、10例、6例;以手術(shù)病理確診結(jié)果為標(biāo)準(zhǔn),MRI對(duì)本組腦膜瘤腫瘤的檢出率為91.7%;腫瘤的形態(tài)主要為圓形或橢圓形、半月形,直徑在3-5cm之間,大小在1.2cm×1.0cm×1.3cm-6.2cm×4.6cm×6.1cm之間;在T1WI呈等信號(hào)58例,呈稍低信號(hào)29例,呈混雜不均勻信號(hào)9例;在T2WI呈稍高信號(hào)46例,呈等信號(hào)21例,呈低信號(hào)21例,呈混雜不均勻信號(hào)8例;增強(qiáng)掃面后,明顯強(qiáng)化的有88例,強(qiáng)化不均勻有8例;67例可見明顯的腦膜尾,38例腫瘤周圍顯示有水腫帶,63例腫瘤在T1WI上可見環(huán)狀低信號(hào),27例局部顱蓋骨增厚。結(jié)論 MRI在腦膜瘤的診斷過(guò)程中,不僅能夠定位診斷出腫瘤的發(fā)育部位、大小、形態(tài),還能通過(guò)綜合分析腦膜瘤的MRI影像表現(xiàn)與病理特點(diǎn)進(jìn)行定性診斷,具有重要的臨床應(yīng)用價(jià)值,值得進(jìn)一步推廣和應(yīng)用。
[Abstract]:Objective to evaluate the value of MRI in the diagnosis of intracranial meningioma. Methods the MRI findings of 96 patients with meningioma received from January 2014 to December 2015 were analyzed retrospectively, and the size, location and morphology of the lesions were analyzed. The detection rate and pathological characteristics were analyzed. Results all the 96 cases of meningioma were single tumors, of which 39 cases were located on the protuberance of the top brain, the anterior skull base, the middle cranial fossa base, the posterior skull base and the parietal cerebral falx. There were 23 cases, 18 cases, 10 cases, 6 cases, respectively. The positive rate of MRI in meningioma was 91.7, the shape of the tumor was mainly round or ellipse, semilunar shape, diameter between 3-5cm, size between 1.2cm 脳 1.0cm 脳 1.3cm-6.2cm 脳 4.6cm 脳 6.1cm, in T1WI, 58 cases showed isointense signal, 29 cases showed slightly low signal intensity. There were 9 cases of mixed heterogeneous signal, 46 cases of slightly hyperintense signal, 21 cases of isointense signal, 21 cases of low signal intensity and 8 cases of mixed heterogeneous signal. There were 8 cases with heterogeneous enhancement and 67 cases with obvious meningeal caudate. In 38 cases, edema band was found in 63 cases. On T1WI, 27 cases of local skull bony thickening were seen on T1WI. Conclusion in the process of diagnosis of meningioma, MRI can not only locate the location, size and shape of the tumor, but also make qualitative diagnosis by synthetically analyzing the MRI imaging features and pathological features of meningioma. Has important clinical application value, is worth further promotion and application.
