Paragangliomas de la cauda equina: a propósito de dos casos

Extraadrenal paragangliomas involving the spinal cord are not common and usually take the compression of the cauda equine. Two cases of paraganglioma of the cauda equina with a different presentation are reported, and the clinical and histopathology findings of this tumor, as well as diagnosis, treatment and prognosis are review. We stress the importance of the high tumor vascularization form of intradural that can make impossible achieve a complete resection. Laminotomy and intraoperatory echography are very useful in the approach to intradural tumors, such as paraganglioma.
