Oligodendrogliomas are a type of glioma that are believed to originate from the oligodendrocytes of the brain or from a glial precursor cell. They occur primarily in adults (9.4% of all primary brain and central nervous system tumors) but are also found in children (4% of all primary brain tumors). With a 0.2 incidence rate out of 100,000 adults, oligodendrogliomas comprise approximately 5% of all central nervous system tumors.
