    Abstract:
    Myxopapillary ependymomas represent the most frequent type of ependymomas found at the conus medullaris-cauda equina-terminal filum level. In this article the authors describe the clinical presentation, radiographic findings, operative details, and pathological features of a patient with a concomitant presentations of a thoracic spinal cord myxopapillary ependymoma and a filum terminale myxopapillary ependymoma. A 16-year-old man presented to the Neurosurgery Department of the S. Maria delle Grazie Hospital (Naples, Italy) with an increased weakness of both the legs with great difficulties with walking and with bowel and bladder dysfunction. In a few minutes he becomes paraplegic. Magnetic resonance (MR) imaging revealed two ependymomas: the first one was localized in the middle thoracic part of the spinal cord and, the second one was localized in the cauda at sacral level. Two operations were performed for gross total resection of the masses. The first operation was performed at thoracic level and the second one was performed at the sacral level after two months. The examination demonstrated in both cases a myxopapillary ependymoma. The patient experienced complete resolution of her preoperative symptoms. This article reports an unusual case of a concomitant presentations of a thoracic spinal cord myxopapillary ependymoma and a filum terminale myxopapillary ependymoma myxopapillary. To the best of the authors' knowledge, this association has not yet been reported. This raises the interesting question of a possible associative or causative relationship between these pathologies. The authors considered dissemination to be the spread of tumor along the neuraxis to a location separate from the primary site. They do not believe that the lesion at the cauda level was a drop metastase. As the entire spinal cord and the brain were imaged, and as the tumor in the thoracic spinal cord area was we well capsulated, a disseminated ependymoma was confidently excluded.
