MRI在大脑镰旁脑膜瘤诊断中的应用价值

目的探讨MRI在大脑镰旁脑膜瘤诊断中的应用价值。方法回顾性分析我院2013年12月-2015年12月期间接收诊治的81例大脑镰旁脑膜瘤患者的临床资料和MRI影像学资料,综合分析大脑镰旁脑膜瘤的MRI影像特征及病理特点。结果 81例患者共发育肿瘤92个,其中单发患者74例,多发患者7例,前、中、后1/3大脑镰旁脑膜瘤患者分别有23例、28例、30例;瘤体直径在1-8cm之间,形态呈半球状有86个(约占93.5%),结节状有6个(约占6.5%);MRI对大脑镰旁脑膜瘤患者肿瘤的定性诊断符合率为91.3%(84/92),定位诊断符合率为86.42%,且与病理学诊断结果相比较,差异无统计学意义(P0.05);本组81例患者中有56例患者的肿瘤在T_1WI为等信号、19例T_1WI为稍低信号,45例在T_2WI为等信号,30在T_2WI为稍高信号,6例在T_1WI及T_2WI均为混杂不均匀信号。结论MRI在对大脑镰旁脑膜瘤患者的临床诊断中,能够清楚地显示出肿瘤的发育部位、数目、大小、形态及其与周围脑组织的关系,并且对肿瘤的电信号及肿瘤内部血供量变化等能够表现出明显强化的作用,其大脑镰旁对脑膜肿瘤的定位诊断及定性诊断都具有较高的诊断符合率,在临床中可以作为一种首先的检查方法,值得进一步推广和应用。

The Application Value of MRI in the Diagnosis of Cerebral Falx Meningioma

Objective To investigate the application value of MRI in the diagnosis of cerebral falx meningioma.Methods Retrospective analysis of the clinical data and MRI data of 81 cases of cerebral falx meningioma patients in our hospital received during the diagnosis and treatment during December 2013 to December 2015.Comprehensive analysis of MRI features of cerebral falx meningioma and pathological features.Results A total of 81 patients developed 92 tumors,including single patients in 74 cases,7 cases of patients with multiple.Before,during and after 1/3 of cerebral fax meningioma were 23 cases,28 cases,30 cases.The tumor diameter between 1-8cm morphology was hemispherical 86 (about 93.5％),nodular 6 (about 6.5％).MRI of cerebral falx meningioma tumor qualitative diagnosis coincidence rate was 91.3％ (84/92),localization diagnosis with rate was 86.42％,and with pathological diagnosis results compared,the difference was not statistically significant(P＞0.05).This group of 81 patients with tumors of 56 patients in the T1WI signal,19 cases of T1WI slightly low signal,45 cases in the T2WI signal,30 in T2WI is slightly high signal in 6 cases,T1WI and T2WI are not uniform signal.Conclusion MRI of cerebral falx meningioma patients with clinical diagnosis of,can clearly display the development of cancer in the site,number,size,shape and its relationship with the surrounding brain tissue,and the tumor signal and tumor blood supply variation and showed obvious enhancement of the role,the falx of meningeal tumor diagnosis and qualitative diagnosis has high diagnostic coincidence rate and in clinical practice can be as a first inspection method.It is worthy of further promotion and Application.
