目的讨论中枢神经细胞瘤的影像学表现,以提高认识和诊断水平。方法回顾性分析经手术病理证实的中枢神经细胞瘤15例的CTMRI表现。结果13例肿瘤均位于双侧侧脑室透明隔或第三脑室Monro孔处,分别向一侧或两侧侧脑室内生长,肿瘤呈不规则形,边缘清楚。CT平扫呈略高密度,密度不均匀,增强扫描轻度强化。MRI表现为略长T1长T2信号,病灶内可见小的囊变灶,注射Gd-DTPA后,病变轻度强化。结论中枢神经细胞瘤CT和MRI诊断具有一定的价值,尤其是MRI。
Objective To discuss the imaging findings of central neurocytoma in order to improve the level of awareness and diagnosis. Methods The CTMRI findings of 15 patients with central neurocytoma confirmed by surgery and pathology were retrospectively analyzed. Results All the 13 tumors were located in the Monro holes of the bilateral or the third ventricle. The tumors grew to one side or both sides of the ventricle. The tumors were irregular and the margin was clear. CT scan slightly higher density, uneven density, enhanced scan mild enhancement. MRI showed a slightly longer T1 long T2 signal, small cystic lesions can be seen within the lesion, Gd-DTPA injection, the lesion was mildly enhanced. Conclusion CT and MRI diagnosis of central neurocytoma have some value, especially MRI.
