PNET and Ewing sarcoma are pathologically distinct entities with very similar clinical and radiological characteristics. Immunohistochemical studies are needed to distinguish PNET from Ewing sarcoma, with the former being characterized by neural differentiation. We present the case of a 17-year-old man with immunohistochemically confirmed PNET in the cervical vertebrae.

UI	MeSH Term	Description	Entries
D008279	Magnetic Resonance Imaging	Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.

D012512	Sarcoma, Ewing	A malignant tumor of the bone which always arises in the medullary tissue, occurring more often in cylindrical bones. The tumor occurs usually before the age of 20, about twice as frequently in males as in females.

D018242	Neuroectodermal Tumors, Primitive	A group of malignant tumors of the nervous system that feature primitive cells with elements of neuronal and/or glial differentiation. Use of this term is limited by some authors to central nervous system tumors and others include neoplasms of similar origin which arise extracranially (i.e., NEUROECTODERMAL TUMORS, PRIMITIVE, PERIPHERAL). This term is also occasionally used as a synonym for MEDULLOBLASTOMA. In general, these tumors arise in the first decade of life and tend to be highly malignant.
