Abstract
AbstractParagangliomas of the cauda equina are tumors of rare incidence, with ~ 220 cases described in the world literature. They are benign lesions, grade I by the World Health Organization (WHO), whose definitive diagnosis can only be made by immunohistochemical analysis. Its neuroendocrine nature is evidenced by the presence of chromogranin. The relevance of reporting this case is because paragangliomas of the cauda equina should be included among the differential diagnoses of intradural and extramedullary tumors, and especially because they can cause perioperative and intraoperative hypertensive crises by adrenergic discharge.The present study presents the case of a 36-year-old male patient diagnosed with a lumbar spine tumor located in the central spinal canal that presented as cauda equina syndrome involving 4 months of bilateral sciatica, paraparesis, urinary and fecal retention. The diagnosis of paraganglioma was confirmed by immunohistochemical positivity for chromogranin after microsurgical resection of the tumor.
