Tanycytic tumors of the cauda equina region are being increasingly reported. Such tumors can occur among pediatric patients and adults. An unusual case of tanycytic ependymoma located at the region of the cauda equina is reported in a girl. The clinical presentation, radiological features, intraoperative findings, and histopathologic features are described. The prognostic significance of differentiating such a neoplasm from other intramedullary tumors is noted. A heightened awareness of this pathologic entity among neurosurgeons and pathologists will help in diagnosing this neoplasm and in enabling better patient management.
