Most oligodendrogliomas occur in patients aged 20-50. Low-grade tumors are more common in younger patients. Seizures are a common presentation. Headaches and focal neurologic symptoms may occur but are uncommon clinical presentations. These are slow-growing tumors and may be clinically silent for years. Median survival ranges from 5-15 years. Survival is longer in younger patients, those with a complete resection, and those with lower-grade tumors.
