      摘要 目的:研究脑室外室管膜瘤的磁共振成像(MRI)影像表现与病理特征的相关性。方法:选取2016年2月-2018年2月我院收治的脑室外室管膜瘤患者40例为研究对象。对所有患者均进行颅脑MRI平扫以及增强扫描检查,分析所有患者的临床病理特征情况,对比不同病理分级、不同病灶直径以及不同病灶部位患者的MRI表现。结果:脑室外室管膜瘤患者中病理分级为Ⅰ-Ⅱ级人数占比为75.00%,高于Ⅲ级的25.00%;病灶直径<6 cm人数占比为40.00%,低于病灶直径≥6 cm的60.00%;病灶部位在幕上的人数占比为20.00%,低于在幕下的80.00%。其中21例肿瘤实质部分均呈现稍长T1和稍长T2信号,另有19例肿瘤实质部分均呈等长T1和等长T2信号;所有患者的肿瘤囊性部分均呈长T1和长T2信号。病理分级为Ⅰ-Ⅱ级患者病灶位于浅表的人数占比明显高于Ⅲ级(P<0.05),病灶直径<6 cm患者合并周围水肿的人数占比高于病灶直径≥6 cm患者(P<0.05),病灶部位为幕上患者的MRI表现和病灶部位为幕下患者对比差异无统计学意义(P>0.05)。结论:MRI应用于诊断脑室外室管膜瘤效果明显,可清晰显示脑室外室管膜瘤病灶,且患者的MRI影像表现受病理分级、病灶直径影响。
英文摘要:
      ABSTRACT Objective: To study the correlation between magnetic resonance imaging (MRI) features and pathological features of extra ventricular ependymoma. Methods: A total of 40 patients with extra ventricular ependymoma, who were treated in Second Affiliated Hospital of Shenyang Medical College from February 2016 to February 2018, were chosen as research subjects.All the patients underwent MRI scan and enhanced scan. The clinicopathological features of all the patients were analyzed. MRI imaging features of the patients with different pathological grade, lesion diameters and lesions location were compared. Results: The proportion of pathological grades with gradeⅠ-Ⅱin the patients with extra ventricular ependymoma was 75%, which was higher than 25.00% of grade Ⅲ. The proportion of lesion diameter <6 cm was 40.00%, which was lower than 60.00% of lesion diameter ≥6 cm. The proportion of lesions location on the curtain was 20.00%, which was lower than 80.00% of lesions location under the curtain. Among them, there were 21 cases with slightly longer T1 and slightly longer T2 signals in the tumor parenchyma, in addition, there were 19 cases with equal length T1 signals and equal length T2 signals in the tumor parenchyma, and all the patients showed long T1 and long T2 signals in the cystic part of tumor. The proportion of superficial lesions in the patients with pathological grade with grade I-II was significantly higher than that of grade III (P<0.05). The proportion of the patients with peripheral edema with <6 cm in the lesion diameter was higher than that of the patients with ≥6 cm in diameter greater(P<0.05). There was no significant difference in the MRI imaging features between the patients with lesion location on the curtain and with lesion location under the curtain(P>0.05). Conclusion: The effect of MRI on ependymoma of the ventricle is obvious, and it can clearly display the lesion of ependymoma of the ventricle,and MRI imaging features of patients are affected by pathological grade and lesion diameter.
