Drop foot and adult onset tethered cord syndrome caused by filum terminal ependymoma: A case report

Abstract

Introduction: Filum terminal is a fibrous tissue to stabilize the position of the spinal cord, located in both intradural and extradural sections anchored caudally to the coccyx. Tumors located at the filum terminal are a rare case. Filum terminal does not have any spinal cord component, but tumours in that area can directly cause a significant neurological disorder. 

Case Presentation: Presenting 43 years old man with chief complaints of drop left foot and tethered cord syndromes. MR Image revealed 9,4x10mm intradural extramedullary mass at L1 with L1-L5 disc desiccation. The patient was untethered by laminectomy and underwent total mass excision. The sample was analyzed pathologically, and the results matched myxopapillary ependymoma. Pain sensation and sensory disturbance immediately improved after surgery. The urinary disorder also gradually improved. The patient was discharged without any urinary problems. After six months of follow-up, painless, mild left lower drop foot and mild gait disturbance was found without residual urinary and other neurological disorder.

Conclusion: Filum terminal ependymomas need to be considered for differential diagnoses in patients with drop foot and adult-onset tethered cord syndromes.
