Primary dorsal spine primitive neuroectodermal tumor in an adult patient: Case report and literature review

Satyashiva Munjal et al. J Craniovertebr Junction Spine. 2017 Oct-Dec.

Abstract

Primary spinal primitive neuroectodermal tumor (psPNET) is a rare entity with few cases reported in literature. We report a case of a 50-year-old female who presented to us with paraplegia and was diagnosed with extradural dorsal spine psPNET. The diagnosis was not suspected at presentation or on radiology but was established on histopathological examination. It is important to distinguish it from central nervous system primitive neuroectodermal tumors and from other spinal tumors since it follows a different clinical course and therapeutic outcome.

Keywords: Adult; dorsal spine; extradural; primitive neuroectodermal tumor.
