Paraganglioma exclusive of filum terminale

A 39-year-old man presented with complaint of right lumbosciatic pain worsened by walking for 6 months. Magnetic resonance imaging showed a cauda equine lesion, suggestive of myxopapillary ependymoma (Fig. 1). The patient was submitted to laminectomy with microsurgical identification of violaceous encapsulated lesion adhered exclusively to the filum terminale. An uneventful en bloc complete resection was performed with total pain and claudication relief. Histopathologic examination and immunohistochemical panel confirmed the lesion to be paraganglioma (Fig. 2).
