侧脑室中枢神经细胞瘤的MRI分析

MRI Analysis of the Central Nervous System of Lateral Ventricle

目的:分析侧脑室中枢神经细胞瘤的MRI表现。方法:回顾性分析经手术证实的CNC6例。男4例,女2例,年龄15-48岁,平均年龄38.5岁。结果:本组6例病例肿瘤均位于侧脑室透明隔近孟氏孔处。在MRI T1WI像呈不均匀等或低信号,T2WI呈不均匀高信号,肿瘤内可有囊变区,增强扫描呈不均匀中等强化,边界清楚。结论:中青年位于侧脑室腔明隔的肿瘤,应考虑致CNC的可能。结合临床及MRI表现有助于此病的诊断。

Objective： To analyze the MRI findings of the lateral ventricle. Methods： The clinical data of CNC 6 cases confirmed by operation were analyzed retrospectively. There were 4 males and2 females with an average age of years（range, 15-48 years）. Results： 6 cases of this group of tumors were located in the lateral ventricle near the foramen of Monro at septum pellucidum. In MRI T1 WI, such as uneven or low signal, T2 WI showed uneven high signal, the tumor can have cystic change area, enhanced scan showed uneven moderate enhancement, clear boundary.Conclusion： CNC should be considered in young and middle-aged patients with tumors located in the septum of the lateral ventricle. Combined with clinical and MRI findings, it is helpful for the diagnosis of the disease.
