Resection of a large thoracolumbar intradural ependymoma: a 2D operative video

In this video, the authors present the resection of a large thoracolumbar intradural ependymoma in a 33-year-old female. The patient underwent T9–L3 laminectomies, intradural tumor resection, and posterior instrumented fixation and fusion. The surgical procedure aimed to relieve the mass effect, obtain a diagnosis, prevent further neurological decline, and achieve a potential curative resection. The pathology confirmed a myxopapillary ependymoma, a rare tumor with a preference for the conus medullaris, cauda equina, or filum terminale. The video provides insights into the case, surgical steps, clinical outcomes, and background information on myxopapillary ependymomas and treatment options.
