Abstract: Children's brain tumors are the common tumors in children,which males are frequently affected than females,and most of patients are children aged 5-14 years old.The incidence rate of infratentorial tumor is higher than that of supratentorial tumor.The cases of infratentorial tumor in children accounted for 60%,and the main part is the fourth ventricle,followed by cerebellar hemisphere and cerebellar vermis,which often occurred in posterior fossa and near the midline.The main part of supratentorial tumor is the cerebral hemispheres,followed by the third ventricle and lateral ventricle.The clinical symptoms of childhood brain tumors are different with the size,characteristics,location and the damage around brain structure.The histopathological types of children's brain tumors are significantly different from that in adults.The benign tumors rarely happen in children,but the incidence rate of glioma in children is greatly higher than that in adults.The mostly pathological types were astrocytoma,medulloblastoma,ependymoma,germ cell tumor and craniopharyngioma.The diagnosis of brain tumor in children should pay attention to the pediatric clinical characteristics,atypical clinical manifestation and detailed medical history,especially the correct and complete symptoms.Then according to the actual situation,it is urgent to carry out the necessary examination,to confirm the diagnosis and reduce the early misdiagnosis rate.The imaging examination plays a very important role in the diagnosis of children's brain tumors,so CT and MR examinations should be carried out in suspected cases as soon as possible.Surgical resection is the first choice,and reasonable postoperative radiotherapy can consolidate the operation effect and prolong survival duration.The radiotherapy accompanied with chemotherapy can improve the curative effect in malignant tumor patients after surgery.
