Primitive neuroectodermal tumors are the most common malignant tumors of the childhood and early childhood. Primary spinal primitive neuroectodermal tumor (PNET) are rare. In recent years the number of patients have entertained increased awareness of PNET, and more than 80 cases have been reported. At every level of the spinal region, and in each compartment spinal PNET may be seen, Although its intramedullary, intradural-extramedullary, and extradural components can be easily excised, and combination treatment can be applied, the longest survival period hardly approaches six years. A case of a spinal PNET resembling to a primary tumour in a 17 -year- old patient who applied with a L1 fracture was presented.
