spinal paraganglioma
Spinal cord paragangliomas are uncommon. More than 120 CNS paragangliomas have been documented, and are most frequently found in the region of the cauda equine and filum terminale, although they have also been reported in the thoracic and cervical regions.
In a study of 30 spinal paraganglioma cases by Moran et al, 19 were located in the lumbar region, 6 in the cauda equina, 2 in the filum terminale, 2 in the thoracic region, and 1 in the cervical region. In another study, 30 of 31 tumors originated in the cauda equina, and 25 of these arose from the filum.
Although cauda equina paragangliomas are categorized as a WHO grade 1, and are usually well-demarcated, encapsulated, and slow-growing, locally invasive and recurrent tumors have been reported.
