[Paraganglioma of the cauda equina]. / Paraganglioma de la cauda equina.

The case of a 36 year old woman with a paraganglioma of the cauda equina was studied. This localization is rare and special emphasis is made concerning the peculiarities of presentation, aggravating factors of the clinical manifestations and neuroradiologic findings. A review of the 66 paragangliomas of the cauda equina published to date is carried out. This entity deals with a tumor in the adult, with slight male predominance and a clinical presentation not differing from that of other lesions occupying the space of the cauda equina. The most frequent initial symptom is low back pain with or without sciatic irradiation. Total resection of the tumor may cure the patient.
