目的探讨侧脑室中枢神经细胞 瘤的临床、病理表现和特征性MRI表现， 以提高对本病诊断准确率。方法 回顾性 分析12例经病理证实的中枢神经细胞瘤的 MRI表现，总结其MR特征。结果 肿瘤均位 于侧脑室，靠近透明隔，以实性部分为 主,伴有多发囊性变，肿瘤实质部分均呈 等T1等T2信号，内部可见多发囊变区， FLAIR序列显示病变边缘清晰，呈不规则 形，内部呈等高信号,增强扫描后肿瘤呈 不均匀轻度强化,病变侧均可见梗阻性脑 积水。结论 MRI对该病的诊断及鉴别诊断 具有较大的价值,可以帮助临床医生选择 正确的治疗方案。

Objective Explore the clinical syndrome，pathological change and characteristic MRI appearance to improve the diagnostic accuracy of central neurocytoma in the lateral ventricles. Methods Retrospectively analyze 12 cases MRI findings of central neurocytoma in the lateral ventricles which proved by pathology. Results All tumors located in lateral ventricles and closed to septum pellucidum, the tumors were mainly solid part, With multiple cystic degeneration, the parenchyma of central neurocytomas showed isointensity on T1WI and T2WI, multiple cystic areas inside, FLAIR sequence showed a lesion with clear edge, irregular shape, isointensity and high signal. The tumors showed mildly inhomogeneous enhancement after enhanced. Obstructive hydrocephalus could be seen. Conclusions MRI has a huge value in diagnosing and distinguishing central neurocytoma, which can help clinicians find the right therapeutic regimen.
