血管母细胞瘤(hemangioblastoma)又称血管网织细胞瘤、Lindau瘤等,属血管源性无包膜肿瘤,约占中枢神经系统肿瘤的1.1%～2.4%,可发生于脑的任何部位,90%以上位于小脑半球,但幕上罕见,其影像学表现有一定特征性。MRI具有组织分辨力高、幕下结构显示无骨骼伪影、多方位成像等优点,是神经系统疾病检查的最佳手段。本研究采用MRI对18例血管母细胞瘤进行检查, Hemangioblastoma, also known as hemangioblastoma, Lindau’s tumor, is an angiogenic non-enveloped tumor, accounting for 1.1% -2.4% of central nervous system tumors, which can occur in any part of the brain, 90 % Above the cerebellum hemisphere, but rare on the screen, the imaging performance of a certain characteristic. MRI has the advantages of high tissue resolution, infratemporal structure shows no bone artifacts, multi-directional imaging and other advantages, is the best means of neurological disease examination. In this study, 18 cases of hemangioblastoma were examined by MRI,
