A rare case of extradural Ewing sarcoma of the cervical spine in a 9-year-old boy

Pediatric embryonal tumors have a rare occurrence in the peripheral nervous system. A more aberrant location is the extradural space, with only 25 cases being reported in literature. The seemingly innocuous symptoms can often be misleading as a sprain, and in our country, where tuberculosis is endemic, it can even be perceived as Pott’s spine, and therefore, leads to a delayed intervention for these rapidly progressive malignancies. We report the case of a 9-year-old boy whose symptoms started with a dull neck pain that was ignored for 6 months as a neck sprain. X-ray of his cervical spine showed only subtle loss of cervical lordosis, a finding that was missed. Eventually, he developed weakness of the right upper and lower limbs and was referred to our hospital. Magnetic resonance imaging revealed a large lobulated extradural lesion extending from C1-D3 level of neoplastic etiology. Postlaminectomy, the histopathology was consistent with primitive embryonal tumor. The patient was immediately started on an intensive chemotherapy regimen and is currently in the consolidation phase.
