摘要
目的 :探讨MRI对儿童后颅窝肿瘤的诊断价值。方法 :回顾性分析 36例经临床和手术病理证实的儿童后颅窝肿瘤患者的MRI和临床资料 ,其中星形细胞肿瘤 13例 ,髓母细胞瘤 7例 ,室管膜瘤 2例 ,少枝胶质细胞瘤 1例 ,血管网状细胞瘤 4例 ,海绵状血管瘤 3例 ,蛛网膜囊肿 2例 ,上皮样囊肿 2例 ,脑膜瘤 1例 ,生殖细胞瘤 1例。结果 :肿瘤位于小脑半球 10例 ,脑干 9例 ,小脑蚓部 8例 ,桥小脑角区 4例 ,第四脑室 3例 ,枕大池 2例。肿瘤位于脑干外 ,但引起脑干受压变形 9例。MRI所示肿瘤的生长部位与手术完全符合 ,MRI定性诊断与病理符合率为 91.3%。结论 :MRI能准确地显示儿童后颅窝肿瘤的部位、大小、形态与周围结构的关系 ,对儿童后颅窝肿瘤的定位定性诊断、治疗具有重要的指导价值。
Objective: To evaluate the MRI diagnosis of posterior fossa tumors in children. Method: MRI and clinical retrospective studies were carried out in 36 children with posterior fossa tumors. There were 13 astrocytomas, 7 medulloblastomas , 4 hemangioblastomas, 3 cavernous angiomas, 2 ependymomas, 2 arachnoidcyst, 2 epidermoid-cysts, 1 meningioma, 1 oligodendroglioma, 1 germinoma. Result: 10 cases located in cerebellar hemisphere, 9 cases in brainstem, 8 cases in vermis, 4 cases in cerebellopontine angle , 3 cases in fourth ventricle, 2 cases in cisterna magna. The tumor locations of MRI were as same as the operations ,as far as the qualitative diagnosis of tumors , the accuracy of MRI is 91.3% as much as pathologic study. Conclusion: MRI is valuable for diagnosis and treatment of posterior fossa tumors in children.
