چکیده
Intrathecal paragangliomas are an unusual cause of the cauda equina syndrome. Although well documented in the neuropathology and neurosurgery literature, only one case report has appeared in the radiology literature to date [1]. Recognition of the tumor is important because of its biologic characteristics ; which differ significantly from ependymoma, the tumor with which it is most commonly confused.
