Abstract
BACKGROUND
Paraspinal masses are a relatively uncommon but diverse group of lesions that can be neoplastic or non-neoplastic. Peripheral primitive neuroectodermal tumors of the lumbar paraspinal region with diffuse and strong glial differentiation have never been reported before.
CASE DESCRIPTION
We report a primary paraspinal primitive neuroectodermal tumor with overwhelming glial differentiation in a 23-year-old female patient who presented with intractable right lower extremity pain. The patient underwent a 2-staged operation with gross total resection of the mass followed by intensity-modulated radiation therapy and oral temozolomide, a regimen employed for high-grade intracranial gliomas. Serial imaging revealed no evidence of recurrence after 3 years.
CONCLUSIONS
Although these lesions appear to be exceptionally rare, an approach similar to that of intracranial high-grade glial tumors was effective in our experience. Our patient had no evidence of recurrence at 3-year follow-up.
