Cauda equina paraganglioma: a review.

Although rare, cauda equina paraganglioma (CEP) is definitely established in the table of cauda equina tumours. There are no particular investigations to document its preoperative diagnosis, unless a vasomotor amine syndrome is present to guide the differential diagnostic spectrum. Magnetic resonance imaging is the examination of choice for the presurgical assessment, but there are still overlapping findings, mainly among CEP, ependymoma, schwannoma, and hemangioblastoma.
