ABSTRACT

Introduction: Myxopapillary ependymomas are considered a biologically and morphologically different variant of ependymomas. The most common clinical manifestations of myxopapillary ependymoma of the cauda equina are pain in the lower back, which may be accompanied by radicular pain and other symptoms of lumbosacral radiculopathy.
Case report: The patient was a 59 year old woman who presented symptoms of progressive weakness and sensory disturbances in lower limbs with relapses and remissions. Neuroimaging studies and histological allowed diagnosis of myxopapillary ependymoma, which was presented with atypical form.
Conclusions: We report the case of a patient with a diagnosis of myxopapillary ependymoma, occurring with atypical clinical, with relapses and remissions.
