A la altura del cuerpo vertebral de C3, tumoración bien delimitada de 30×10×14mm sin edema vasogénico asociado ni cavidad a la altura del canal ependimario.
====Tratamiento====
===Quirúrgico===
[[Posición decúbito prono]], sobre [[cabezal de Mayfield]].
Por lo general tienen un plano identificable que permite la realización segura de la extirpación total.
La fenestración unilateral, multinivel, interlaminar permite un buen acceso a un segmento largo intraespinal, protegiendo las estructuras esenciales para la estabilidad de la columna vertebral [(Xie T, Qian J, Wu X, Lu Y, Hu G, Luo C.

====Pronóstico====
Pueden experimentar un empeoramiento neurológico inicial en el postoperatorio inmediato, cuyo riesgo se incrementa en pacientes mayores.
El cincuenta por ciento de los pacientes que experimentan este empeoramiento inicial, muestran una mejoría a largo plazo.
El pronóstico es peor en pacientes en los que no se pudo identificar un plano quirúrgico, independientemente del subtipo de ependimoma [(Garcés-Ambrossi, Giannina L, Matthew J McGirt, Vivek A Mehta, Daniel M Sciubba, Timothy F Witham, Ali Bydon, Jean-Paul Wolinksy, George I Jallo, and Ziya L Gokaslan. 2009. “Factors Associated with Progression-free Survival and Long-term Neurological Outcome After Resection of Intramedullary Spinal Cord Tumors: Analysis of 101 Consecutive Cases.” Journal of Neurosurgery.
