Paragangliomas are rare neuroectodermal tumors arising from both sympathetic and parasympathetic paraganglias Chemodectoma of the carotic sinus and the glomus jugulare tumor represent ninety per cent of these tumors. The authors present a case of a 30 years old man with a nonfunctional paraganglioma of the filum terminale at the L2-L3 level. The tumor was radically removed from the laminotomy and a complete remission of the preoperative symptoms was noted. No signs of recurrence or residual tumor were found at the control MRI six months later. Clinical symptomatology, radiological, histological and imunohistochemical features of paragangliomas in this location are discussed. The radical resection is the therapeutic method of choice that shows excellent results.
