Area of Science:

  • Pediatric Oncology
  • Neuro-oncology
  • Skeletal Tumors

Background:

  • Ewing sarcoma is a rare primary bone tumor in children and adolescents.
  • Intradural extramedullary Ewing sarcoma is exceptionally uncommon, especially with intracranial metastases.

Observation:

  • A 14-year-old female presented with progressive neurological deficits mimicking non-organic causes.
  • Imaging revealed a suprasellar mass, leptomeningeal enhancement, and spinal lesions.

Findings:

  • The patient was diagnosed with primary intradural extramedullary Ewing sarcoma with intracranial metastatic components.
  • Multimodal treatment including surgery, VDC/IE chemotherapy, and radiation led to significant clinical and radiological improvement.

Implications:

  • This case highlights the importance of considering rare diagnoses in pediatric patients with atypical neurological symptoms.
  • Successful management of this rare presentation suggests potential efficacy of combined treatment modalities.
