【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。更多还原

【Abstract】 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.更多还原
