Giant gangliocytic paraganglioma of the filum terminale. Case report.J Neurosurg. 1990 Sep; 73(3):459-61.JN
The clinical and pathological features of a giant cauda equina paraganglioma arising from the intradural filum terminale is described. Scattered mature large neurons characterized the tumor as a gangliocytic paraganglioma. Histologically, these neoplasms have considerable similarity with ependymoma and the diagnosis can be easily missed unless special techniques are employed.
