Abstract
Introduction: Intra-dural and extramedullary ependymomas are rare lesions. We report a clinical case confirmed by the histology supported by the neurosurgery department of Martinique University Hospital. Clinical, paraclinical and therapeutic data will be compared to a literature review. Observation: A 38-year-old patient was admitted for tetraparesthesia evolving since 3 months, associated with a left hemiparesis. The clinical examination revealed deterioration of the general condition and a tetrapyramidal syndrome. MRI of the cervical spine revealed extensive cervical extra-medullary intradural lesion of C3 to C5. The treatment had been an excisional surgery that had been subtotal in two stages, supplemented by craniospinal radiotherapy because the pathological examination had found a grade III anaplasic ependymoma. Conclusion: Because of their rarity, the treatment of these forms of ependymoma is not yet well codified.

Summary
Spinal ependymomas are glial tumors that develop at the expense of the ependymal coating. Their topography is in the cervicothoracic region [1] [2]. This extra-medullary form of ependymoma accounts for almost 90% of intra-dural extra-medullary tumors with meningiomas, neuromas and neurofibromas [1] [2]. The literature reports rare cases of extramedullary intradural ependymoma excluding those located in the filum and the terminal cone (Table 1)
