Paraganglioma of the Cauda Equina – Case Report and Literature Review

Abstract

Paragangliomas 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.
