Table 1.

Patient cohort and clinical information of seventeen cauda equina paragangliomas (CEPs), including personal and family history of neoplasia, maximum size of tumor on imaging, whether gross total resection (GTR) was achieved, length of clinical follow-up, evidence of recurrence, and clinical status at last follow-up. All seventeen cases were assessed by immunohistochemistry (IHC) and twelve cases were studied by DNA methylation profiling as indicated.
