摘要
目的:分析髓母细胞瘤MRI影像学特点.方法:搜集经手术病理证实的髓母细胞瘤12例,行MR检查,其中男9例,女3例,10岁以下病人7例(58%),11~20岁病人5例(42%).结果:髓母细胞瘤好发于男性儿童,常见于小脑蚓部.MRI扫描T1加权像呈等或稍低信号,T2加权像呈等或略高于脑灰质信号,注药后呈中等至明显强化.结论:磁共振影像学检查可以有效的诊断髓母细胞瘤.
Objective:To analyse the MRI features of medulloblastoma.Methods:12 cases with medulloblastoma proved by surgery and pathology undervent MRI scaning.There were 9 male and 3 female in which 7(58%) cases were below 10 years old.The othes 5(42%) cases were 11~20 years old.Results:Medulloblastoma was common in children predominantly in male,frequently involving the inferior vermis.On MRI scan,they appeared iso-and slightly hypointensity on T1WI,iso-or slightly hyperintensity on T2WI with moderate to marked enhancement after contrast injection.Conclusion:The MRI is helpful for diagnosis of diagnosis of medulloblastoma.
