目的:分析脑室内中枢神经细胞瘤(CNC)的MRI表现.材料和方法:对8例经病理证实CNC的MRI表现进行回顾性分析.结果:8例CNC中,位于侧脑室6例,三脑室并累及室间孔1例和单独位于四脑室1例.肿瘤以实性为主5例,伴有不同程度囊变,肿瘤呈囊-实混合性3例,实性部分T1WI呈稍低或等信号,T2WI呈等、稍高或高信号,增强扫描肿瘤实性部分呈中度至明显增强,其中1例三脑室肿瘤呈环形增强.结论:侧脑室CNC MRI表现有一定特征,结合临床特征,术前多能够做出正确诊断,而三脑室、四脑室的CNC的影像表现缺乏特征,诊断依靠病理.

Purpose To analyze MRI manifestations of central neurocytoma(CNC) in cerebral ventricle. Materials and Methods MRI features of 8 patients with CNC pathologically proved were studied retrospectively. Results: The tumors were located in the lateral ventricles in 6 cases. One tumor was in the third cerebral ventricle involving the interventricular foramen. One was located in the fourth cerebral ventricle. Five of the tumors were mainly composed of solid mass accompanied by multiple cysts and the rest ones were composed of solid-cyst combination.The solid mass presented as iso-intensity signal or slight hypo-intensity sigal on T1WI and iso-intensity signal, slight hyper-intensity signal or hyper-intensity signal on T2WI. The solid mass showed moderate or marked enhancement, of which 1 in the third cerebral ventricle showed ring-shaped enhancement. Conclusion MRI manifestations of CNC in the lateral cerebral ventricles are of some characters, Which is helpful in making correct preoperative diagnosis in most cases if combined with clinical information,but the manifestations in the third or fourth cerebral ventricle are short of characters, and the final diagnosis may depends on pathology.
