目的：分析总结中枢神经细胞瘤(CNC)的CT及MRI影像学特征，以对其进行正确诊断。方法对23例经手术病理证实的中枢神经细胞瘤的CT及MRI影像学表现进行回顾性分析，总结其影像特征。结果23例中枢神经细胞瘤多位于侧脑室前部、孟氏孔区，向侧脑室两侧不对称性生长，可见分叶，边界清晰。CT多呈等或稍高密度阴影，其中可见囊变及钙化。MRI表现为肿瘤瘤体信号不均匀， T1WI呈等、稍低或稍高信号，T2WI呈等或稍高信号，肿块可见囊变，钙化或出血，有14例可见肿瘤内的多发性囊肿与侧脑室壁相连。CT和MRI增强扫描见病灶实性部分大多为轻中度强化，囊变和钙化区无强化。结论中枢神经细胞瘤的CT和MRI表现具备一定的特征性，CNC的MR重要征象之一为肿瘤的实性部分和侧脑室壁之间有多发性囊肿相连。

Objective To assess the value of CT and MRI in the diagnosis of central neuroeytoma. Methods CT and MRI findings of 23 cases with central neurocytoma verified by pathology were analyzed retrospectively. Results 23 cases of central neurocytoma were Iocated in the frontal of lateral ventricle adjacent to foramen of Monro. Most of them were irregular in shape, asymmetrically grown to both sides, clearly bounded and lobulated, there was no or only slight edema in brain. The tumor showed iso-or high density on CT imaging. All tumours had heterogeneous signal intensity in their solid components. The lesions demonstrated iso-, slightly hypo-or hyperintense on Tl-weighted image and iso-or slightly hyperintense on T2-weighted image. The tumor showed cystic change and calcification or bleeding in the mass.Fourteen could be seen multiple cysts interfacing between the solid part of the tumour and the lateral ventricular wall. The solid part could be enhanced slightly or moderatedly and the part of cystic change and calcification could not be enhanced on CT and MR images. Conclusion Central neurocytoma have some characteristics on CT and MR images, multiple cystic interfaces between the solid part of the tumour and the lateral ventricular wall on MRI may contribute to a correct preoperative diagnosis of CNC.
