脑室内神经细胞瘤(IN)是新近才认识的发生于青年人的一种良性肿瘤。由于在光镜下形态与少枝胶质瘤相似,病理上二者常混淆。作者报道了6例经病理证实的IN,并与以前报道的26例作比较。临床上IN好发于年轻人,平均年龄为31岁。常表现为头痛(62%),颅内高压(41%)、癫痫(12%),偶有无症状为CT偶然发现者。其预后比胶质瘤好,即使手术切除不完全,症状常消失。作者6例及文献26例均未提及有复发及转移者。IN的病理诊断依赖于肿瘤细胞的神经元裔的显示。放射学上,血管造影无特征性表现。MRT_1及
Intraventricular neuroblastoma (IN) is a newly diagnosed benign tumor in young people. Because of the light microscope morphology and juvenile glioma similar pathological two often confused. The authors reported 6 pathologically confirmed IN, compared with 26 previously reported. IN clinical onset occurs in young people, the average age of 31 years old. Often manifested as headache (62%), intracranial hypertension (41%), epilepsy (12%), occasionally asymptomatic CT findings. Its prognosis is better than glioma, even if the surgical resection is not complete, the symptoms often disappear. There was no mention of recurrence or metastasis in 6 cases and 26 cases in literature. The pathological diagnosis of IN relies on the display of neuronal ancestry of tumor cells. Radiologically, angiography has no characteristic manifestations. MRT_1 and
