title: Symptomatic cerebellar metastasis and late local recurrence of a cauda equina paraganglioma. Case report.
abstract: This case report contains a description of a 61-year-old patient who presented with a progressive truncal ataxia 22 years after complete removal of a small paraganglioma of the cauda equina. Magnetic resonance imaging of the neuraxis revealed a large cystic lesion in the cerebellar midline, three small cortical-to-subcortical nodular tumors in the posterior fossa, and local recurrences of the paraganglioma of the cauda equina. Pathological examination showed the cerebellar midline lesion to be a paraganglioma, most likely a metastasis from the cauda equina localization.
