目的：探讨幕上及幕下脑室中枢神经细胞瘤MRI表现。方法：1999-2013年收集经手术病理确诊的中枢神经经细胞瘤MRI表现资料17例(其中3例为术后复查影像资料)，进行分析。结果：位于侧脑室透明隔区域13例，位于侧脑室后角区域2例，第三脑室及幕下第四脑室各1例。肿块绝大多数呈囊实性混杂肿块影，T1WI呈低信号，其内多发小泡状更低信号影，T2WI呈高信号，夹杂更高泡状影。3例术后复查未见肿瘤复发征象。11例增强扫描肿瘤均呈中等程度或显著强化，囊变成分不强化。结论：幕上侧脑室内中枢神经细胞瘤好发透明隔区域，肿瘤内部多发小泡状影，影像学具有一定特征，而位于侧脑室后角、第三脑室、幕下第四脑室内肿瘤缺乏特征，诊断困难。

Objective:To investigate the MRI manifestations of supratentorial and infratentorial central neurocytoma intraventricular.Methods:We collected 17 cases of MRI performance datas of central nerve cell tumor which confirmed by the operation pathologically from 1999 to 2013(including 3 cases of postoperative examination image datas),and analyzed the datas. Results:Located in the lateral ventricle septum pellucidum region in 13 cases,in the back region of horns of the lateral ventricles in 2 cases;the three ventricle and the screen four ventricle had 1 cases in each.The vast majority of masses with cystic mixed mass shadow;T1WI showed low signal,the multiple vesicles in lower signal intensity;T2WI showed high signal,included more high bubble shadow.Examination showed no signs of tumor recurrence after the operation of 3 cases.11 cases were enhanced scanning showed tumors moderate or marked enhancement,sac into not strengthened.Conclusion:Curtain upper intraventricular central neurocytoma frequently occurs in transparent septum,and tumor internal has multiple vesicles shadows.The imaging has certain characteristics.But for located in the posterior horn of lateral ventricle,the three ventricle,and under the curtain of four ventricle tumors lack of features,the diagnosis is difficult.
