-Filum terminale ependymomas are slow growing tumors of the cauda equina with a high incidence in young adults. Although a complete microsurgical resection can lead to a cure, recurrence is not uncommon. Sixteen cases of filum terminale ependymomas treated at the Instituto de Neurologia de Curitiba were analyzed. Eleven patients were females and 5 males, their age ranging from 7 to 84 years. Symptoms and signs included lumbar pain (31.25%), radicular pain (56.25%) and neurological deficits (12.5%). In three cases, patients had previously undergone surgery in other hospitals. All were tested through MRI and were operated on. Two underwent a laminoplasty and 14 a laminectomy. The last 8 patients of this series had neuro-physiological monitoring during surgery. In all patients a total microsurgical resection was achieved. Histologically, 2 cases were cellular ependymomas and 14 cases myxopapillary ependymomas. There was no recurrence during a 2 to 84 month follow-up period.KEy woRdS: ependymoma, filum terminale, spinal tumor. Ependimoma primário de filum terminale: análise de uma série de 16 casosResumo -os ependimomas do filum teminale são tumores da cauda eqüina de crescimento lento com maior incidência em adultos jovens. A ressecção microcirúrgica total possibilita a cura da doença, recidivas, entretanto, apresentam sérias dificuldades no tratamento. Com o objetivo de estudar os aspectos clínicos, anatomopatológicos e do tratamento, analisaram-se 16 casos de ependimomas do filum teminale tratados no Instituto de Neurologia de Curitiba, 11 do sexo feminino e 5 do sexo masculino, com idade entre 7 e 84 anos, que apresentavam dor lombar (31,25%), radiculopatia (56,25%) e déficits neurológicos (12,5%). Em 3 casos, os pacientes tinham sido operados em outro serviço anteriormente. Em todos os casos o diagnóstico foi confirmado pela ressonância magnética. Em 2 pacientes realizou-se laminoplastia e em 14 laminectomia. Nos últimos 8 pacientes empregou-se monitorização neurofisiológica. Em todos os casos a ressecção microcirúrgica foi total. do ponto de vista histológico, demonstraram-se 2 casos de ependimoma celular e 14 casos mixopapilares. Não houve recidiva do tumor em um seguimento entre 2 e 84 meses.
