血管中心型胶质瘤的研究进展

血管中心型胶质瘤是一种近年来新认识到的致癫痫的脑胶质瘤，目前全世界已报道的病例很少。该肿瘤在临床上主要表现为药物难治性癫痫，组织学特点为形态单一的双极肿瘤细胞以各级血管为中心排列。在影像学上该肿瘤具有T1像皮质呈弥漫性或花边样（rimlike）高密度，T2像呈蒂状（stalklike）延伸至脑室等显著特征。2007年，WHO将其纳入中枢神经系统肿瘤新的分类系统中。

Advances on research of angiocentric glioma

Angiocentric Glioma has been newly identified as an epilepsy associated tumory. Up to now, reported cases are still scarce. The tumor causes drug-resistant epilepsy. On histological findings, monomorphous bipolar tumor cells are arranged around vessels. Imaging studies show that the tumor is diffused or rimlike hyperintensity on T1-weighted SE sequences and a stalklike extension to the ventricle on T2-weighted sequences. The World Health Organization listed this new entity in its fourth edition of the WHO classification of tumors of the central nervous system published in 2007.
