Objective: To investigate the incidence of central nervous system tumors in children. Methods: A retrospective analysis was performed on 766 children with CNS tumors in Huashan Hospital from 1986 to 1998. Results: This group accounted for 6.14% of the cases of central nervous system tumors in the same period. Location: Intracranial 725 cases, of which 499 cases on the screen, 276 cases under the screen, 41 cases of spinal canal. Histological classification: the first three were astrocytic tumors (19 cases, accounting for 26.0%); craniopharyngioma (115 cases, 15.0%); medulloblastoma (101 cases, accounting for 13.2%). Gender: boys more common. Incidence involving all age groups, the number of cases increased with age. CONCLUSIONS: Children with CNS tumors are more likely to be on the screen than those under the screen. Astrocytic tumors are most common in intracranial tumors and 1.50: 1 in boys than in girls.
