Incidence
Brain tumors are the second most common malignancy among children less than 20 years of age. Medulloblastoma is the most common malignant brain tumor, comprising 14.5% of newly diagnosed cases.[1] In adults, medulloblastoma is rare, comprising less than 2% of CNS malignancies.[2]
The incidence of childhood medulloblastoma is higher in males (62%) than females (38%). [3] Medulloblastoma and other PNET tumors are more prevalent in younger children than older children. 40% of medulloblastoma patients are diagnosed before the age of 5, 31% are between the ages of 5 and 9, 18.3% are between the ages of 10 and 14, and 12.7% are between the ages of 15 and 19.
