目的:研究中枢神经细胞瘤的影像学特点。方法:回顾性研究经病理证实的中枢神经细胞瘤12例,男6例,女6例,年龄17-55岁,平均33.8岁,分析其MRI及CT表现。结果:肿瘤均位于透明隔及侧脑室,邻近Monro孔处,5例进入第三脑室,T1WI及T2WI均表现为与皮层灰质相等或略高信号,边缘清楚,体积较大,边缘及内部可见多发囊泡,常见钙化。结论:年轻人透明隔及侧脑室多囊有钙化肿瘤,应高度怀疑中枢神经细胞瘤,MRI是术前诊断中枢神经细胞瘤的最佳影像学方法,CT对肿瘤钙化更为敏感。
Objective: To study the imaging features of central neurocytoma. Methods: Retrospective study of 12 cases of central neuroblastoma confirmed by pathology, 6 males and 6 females, aged 17-55 years, average 33.8 years old, MRI and CT findings were analyzed. Results: Tumors were located in the septum and lateral ventricle, adjacent to the Monro hole, 5 cases entered the third ventricle. Both T1WI and T2WI showed equal or slightly higher signals with cortical gray matter, with clear margin, larger volume, multiple border and internal Vesicles, common calcification. CONCLUSIONS: Young people should have a high degree of suspicion of central neurocytoma with clear septum and polycystic calcification in the lateral ventricle. MRI is the best imaging method for preoperative diagnosis of central neurocytoma. CT is more sensitive to tumor calcification.
