Objective To investigate the clinical manifestations and prognosis of children with cerebellar medulloblastoma. Methods Nine cases of pediatric patients with medulloblastoma all underwent “radical” resection. Results After radical resection, all 9 children with cerebellar medulloblastoma survived and the 5-year survival rate was 100%. Conclusion The operation of pediatric medulloblastoma surgery should be performed without tumor technique. The tumor should be removed 1.5cm beyond the tumor margin under the microscope and the low-dose conventional radiotherapy should be performed after operation.
