小儿髓母细胞瘤与室管膜瘤有什么区别 王东臣 聊城市脑科医院

小儿髓母细胞瘤与室管膜瘤有什么区别 王东臣 聊城市脑科医院 小儿髓母细胞瘤和室管膜瘤都是儿童常见的肿瘤，髓母细胞瘤的发病率比室管膜瘤的发病率相对要高，而且髓母细胞瘤是恶性程度最高的恶性肿瘤，相对室管膜瘤细胞瘤是偏良性的肿瘤，比髓母细胞瘤的预后要少很多，室管膜瘤一般分为三类，一二级相对良性，间变性室管膜瘤属于恶性程度，相对高些的恶性肿瘤。而髓母细胞瘤是恶性程度最高的肿瘤，他的预后比较差，复发率比较高，从影像学上可以适当的鉴别室管膜瘤往往与脑室有一定间隙。而髓母细胞瘤往往与小脑的后髓帆有紧密的联系，界限有些不清楚，但是重要的鉴别点需要病理科检查。 What is the difference between medulloblastoma and ependymoma in children Medulloblastoma and ependymoma are common tumors in children, The incidence rate of medulloblastoma is higher than incidence rate of ependymoma. Medulloblastoma is the most malignant tumor, Compared with ependymoma, it is a benign tumor, The prognosis is much less than that of medulloblastoma, Ependymoma can be divided into three types, The first and second levels are relatively benign, Anaplastic ependymoma is malignant, A relatively high level of malignancy. Medulloblastoma is the most malignant tumor, His prognosis is poor, The recurrence rate is high, There is a certain gap between ependymoma and ventricle. Medulloblastoma is closely related to the posterior medullary velum of cerebellum, The boundaries are not clear, But the important differentiation points need to be examined by pathology department.
