目的研究脑干胶质瘤磁共振成像(MRI)及病理学特点及两者相关性。方法 78例疑似脑干胶质瘤患者,所有患者均采用磁共振成像检查,分析磁共振成像与病理学特点。结果 78例患者中有56例(71.79%)低级别胶质瘤,17例(21.79%)高级别胶质瘤,5例(6.41%)其他病理类型,采用磁共振成像技术检查准确性为96.15%(75/78)。内生局限型病理级别明显低于内生弥散型脑干胶质瘤,外生局限型病理级别明显低于外生弥散型,在内生弥散型中,无强化型病理级别较低,差异均有统计学意义(P<0.05)。成人与儿童脑干胶质瘤病理级别相比,差异无统计学意义(P>0.05)。结论对脑干胶质瘤采用磁共振成像技术检查的准确性较高,但是对于有些类型的肿瘤仍然需要经过病理确诊。
Objective To study the magnetic resonance imaging (MRI) and pathological features of brain stem glioma and their relationship. Methods A total of 78 patients with suspected brain stem gliomas were enrolled. All patients were examined by magnetic resonance imaging (MRI) to analyze the characteristics of magnetic resonance imaging and pathology. Results There were 56 (71.79%) low grade gliomas, 17 (21.79%) high grade gliomas and 5 (6.41%) other pathological types in 78 patients. The accuracy of magnetic resonance imaging was 96.15 % (75/78). Endogenous localized pathological grade was significantly lower than that of endogenous diffuse brain stem glioma, exogenous limited pathological grade was significantly lower than that of exogenous diffuse type, endogenous diffuse type, no enhanced pathological grade were lower, the difference was There was statistical significance (P <0.05). There was no significant difference in the pathological grade between adult and childhood brain stem gliomas (P> 0.05). Conclusion The accuracy of magnetic resonance imaging in the diagnosis of brain stem gliomas is high, but some types of tumors still need pathological diagnosis.
