Presentamos dos casos de quistes epidermoides (colesteatomas) intraespinales dorsales, localización que es poco frecuente. Se trata de dos pacientes que ingresaron en nuestro servicio con diagnóstico de compresión medular, a quienes se les extirpó una tumoración con características macroscópicas y con comprobación posterior por estudio anatomopatológico de quiste epidermoide (colesteatoma), uno de los cuales se localizaba intramedularmente a nivel de D2–D3 y otro localizado intradural extramedular a nivel de D2. Las lesiones fueron estudiadas con RM y extirpadas radicalmente mediante laminectomía. Destacamos la importancia de la RM como método diagnóstico· y de ayuda inapreciable en la planificación quirúrgica.
