[摘要]目的 探讨中枢神经细胞瘤的临床表现、病理改变和特征性MRI表现。方法 回顾性分析5例经病理证实的中枢神经细胞瘤的MRI表现。结果 肿瘤均位于侧脑室，靠近透明隔。MRI上肿瘤实质呈等T1 等T2 信号，内可见囊变区，增强扫描肿瘤呈不均匀轻度强化。结论 起源于侧脑室透明隔的肿瘤，应考虑到中枢神经细胞瘤的可能。

    [ABSTRACT]ObjectiveTo discuss the clinical manifestations， pathologic changes of central neurocytoma and its features on magnetic resonance imaging (MRI). MethodsMRI manifestations of five cases with the neurocytoma confirmed pathologi-cally were analyzed retrospectively. ResultsAll the tumors located in the lateral ventricles and closed to the septum pellucidum. Their parenchyma showed isointensity on T1 WI and T2 WI， with cystic areas. They showed inhomogeneous enhancement after in-tensified scanning. ConclusionCentral neurocytoma should be considered when a mass originates from the septum pellucidum. ......
