 ==Epidemiology and Demographics==
-===Frequency===
+===Incidence===
+The incidence of brainstem gliomas is 300-600 every year.
-In the US, brainstem gliomas have been reported to make up 2.4% of all intracranial tumors in adults and 9.4% of intracranial tumors in children. Brainstem gliomas account for approximately 10-20% of all childhood brain tumors. The incidence in adults is lower than that in children younger than 16 years. A tendency for brainstem gliomas to follow a more indolent course in adults than in children has been noted; in adults, these tumors are more likely to be low grade and remain localized.
-===Sex===
-Some reports have suggested a slight male preponderance, whereas others have failed to observe any sex predilection.
-===Age===
-Bimodal age distribution has been noted, with a peak incidence in the latter half of the first decade of life and a second peak in the fourth decade.
-Approximately three fourths of patients are younger than 20 years.
-Neoplasms of the brain stem have been identified in children younger than 1 year.
