摘　　要：目的：研究小脑血管母细胞瘤的MRI表现,并探讨其临床诊断价值。方法：搜集经MRI诊断及手术病理证实的小脑血管母细胞瘤37例,男性25例,女性12例,年龄8～62岁。所有病例均行MRI平扫和增强扫描,以及液体衰减反转恢复成像（FLAIR）。结果：肿瘤的活性部分于FLAIR和T2WI呈高信号,增强后明显强化;T1WI肿瘤囊性部分呈均匀低信号、肿瘤壁结节呈稍低信号或等信号。MRI表现为囊壁结节型28例（75.7%）,实质型5例（13.5%）,囊旁结节型4例（10.8%）。结论：小脑血管母细胞瘤发生部位、形态对诊断有一定价值,MRI是诊断小脑血管母细胞瘤的可靠方法,MRI增强扫描对小脑血管母细胞瘤的诊断具有重要的价值。Objective：To study MR findings of cerebellar hemangioblastoma and their value in the diagnosis.Methods：37 cases of cerebellar hemangioblastoma underwent MRI and were proved by pathology.There were 25 were males and 12 were females,age range 8～62 years.Plain MR scan and enhanced MR scan and fluid-attenuated inversion recovery（FLAIR） were performed in all cases.Results：Viable part of the lesions displayed hyperintensity on FLAIR and T2W I and could be significantly enhanced;the cyst part displayed an even hypointensity on T1WI,and nodules on the cyst manifested a slight hypointensity or iso-intensity.On MRI,28（75.5%） manifested nodules on cyst wall,5（13.5%） were solid,and 4（10.8%） nodules beside the cyst.Conclusion：The occurrence of cerebellar hemangioblastoma has predilection for certain locations.MRI is a good method for diagnosing cerebellar hemangioblastoma.Enhanced MRI has a great value.
