侧脑室神经细胞瘤

Neurocytoma in lateral ventricle

少枝胶质细胞瘤在脑内多见,而位于侧脑室者比较少,光镜下均诊断为少枝胶质细胞瘤。结合国外文献报告和我院脑内、侧脑室少枝胶质细胞瘤电镜的超微结构检查,结果对比,侧脑室少枝胶质细胞瘤实际应诊断为“神经细胞瘤”根据文献报告及本组病例的观察,此肿瘤对放疗敏感,预后较好。

Oligodendroglioma is mainly found in the cerebralparechyma and is rare in lateral ventricle. Previouslythey were all diagnosed as oligodendroglioma underlight microscope. We examined a series of cases witholigodendroglioma in and out of lateral vertricle un-der electric microscope and found this tumor inlateral ventricle had some special features. We couldsee neuron mutation and within the neuron, therewere many microtubules., neurosecretary granules.mitochondria and chromasome. The immuno-histoche-mical test, neuron-specific enoluse <NSE>ndneurofilament <NF>ere all positive. So accordingto the results and literature report. we suggest thatthe lateral ventricle oligodendroglioma. demonstratedby electric microscope, should be diagnosed as neu-rocytoma. And this tumor is sensitive to radiatherapyand has a good prognosis.
