Épendymomes intramédullaires : étude rétrospective multicentrique française sur 221 cas

Gross total removal remains the mainstay treatment for IE. Early surgery is indicated if the patient is symptomatic or the tumor increases in size. A postoperative regular follow-up is mandatory for at least 10 years due to the risk of recurrence. If a growing residue is detected, a second intervention is recommended without any adjuvant treatment if a WHO grade I lesion is confirmed by the pathological analysis. Complementary treatment should be reserved for high-grade ependymomas or in case of unresectable and progressive residue.
