Paraganglioma of the cauda equina with associated intramedullary cyst: MR findings.AJNR Am J Neuroradiol. 1997 Sep; 18(8):1588-90.AA
The MR imaging features of a paraganglioma of the cauda equina with associated spinal cord cysts are presented. MR imaging showed the tumor to be isointense with the spinal cord on all pulse sequences and to enhance homogeneously. The intramedullary cysts had increased signal intensity on proton density- and T2-weighted images, and involved the cervical and thoracic regions.
