Anaplastic clear cell ependymoma of the conus medullaris and cauda equina in a 3-year-old child.

Only a minority of ependymomas present in the spinal cord. We report on a child with recurrence of a rare anaplastic clear cell type of ependymoma. This was initially misdiagnosed as a World Health Organization grade I myxopapillary ependymoma because this type of ependymoma occurs more commonly and the magnetic resonance imaging features and location at the conus medullaris were considered characteristic.
