Primitive neuroectodermal tumors (PNET) are rare, and are even rarer when they arise from the spinal cord tissue. Therefore, we report a case of peripheral PNET that arose from the sacral spinal nerve root.

We performed surgery to remove the tumor, and confirmed total resection. Our subsequent pathological testing confirmed a diagnosis of peripheral PNET, and we elected to treat the patient using concurrent radiotherapy and the standard chemotherapy for Ewing’s... view more»
