Resection Methods of Cervical Medullary Tumors with Mixed Histological Characteristics

Abstract

The Subependymoma is derived from subependymal astrocytic cells. In the present work we report 3 patients: 1 patient with data of endocranial hypertension, and two with neurological focus and spinal involvement. MRI (Magnetic Resonance Imagen) showed heterogeneous images, solid and cystic components, from different locations. Ependimo-Astrocytomas have neoplastic ependymal cells and gliofibrillar formation.
