Subependymoma in the third ventricle in a child

Subependymomas are rare, slow-growing, benign intraventricular tumors which occur commonly in the fourth or lateral ventricle. They usually occur in elderly men and often are asymptomatic and discovered incidentally. We report a case of a 6-year-old girl with a symptomatic subependymoma in the third ventricle with MR imaging.
