Magnetic resonance imaging of paraganglioma of the cauda equina.Can Assoc Radiol J. 1995 Feb; 46(1):37-9.CA
The authors describe atypical magnetic resonance imaging (MRI) findings for pathologically proven paraganglioma of the filum terminale in a 27-year-old man. MRI showed an intradural tumour, which enhanced after administration of gadolinium and which showed evidence of cystic areas. Hemosiderin rings and vessels were not observed.
