Primary primitive neuroectodermal tumor within the spinal epidural space: report of a case and review of the literature.Neurol Res. 2004 Oct; 26(7):774-7.NR
Primary intraspinal primitive neuroectodermal tumors (PNETs) are rare tumors and a have poor prognosis. In reviews of the literature, it is seen that primary intraspinal PNETs may arise at all levels of the spine and may be intramedullary, intradural-extramedullary, or epidural. Spinal epidural location of PNET is extremely rare and out of 22 cases of primary spinal PNETs reported to date, only two were epidural. Tumors within the epidural space of the spinal canal are most often metastatic neoplasms from different primary sites. Here we report a case of primary extradural PNET located in the thoracic spine in a 16-year-old boy and review the relevant literature.
