Primary intraspinal primitive neuroectodermal tumors (PNETs) are rare. We report a 3-year-old boy presented with rapidly progressive paraparesis and neurogenic bladder. A thoracolumbar magnetic resonance imaging demonstrated an intrasipnal mass from the T12 to L3 level. An operation was performed with gross total tumor removal. Histologic examination revealed a small round cell tumor and immunohistochemical characteristics of PNET. There was no clinical or radiological evidence for existence of intracranial tumor. The parents denied chemotherapy and radiotherapy. Metastases to lung was noted at 6 months after surgery and died due to respiratory failure at his local hospital. The clinical, imaging, and pathological features are discussed with a review of the literature.
