Area of Science:

  • Pediatric Oncology
  • Neurosurgery
  • Spinal Tumors

Background:

  • Primitive neuroectodermal tumors (PNETs) represent a complex group of neoplasms with evolving classification and nomenclature.
  • Primary intraspinal PNETs are exceptionally rare, particularly in pediatric populations, and are associated with a generally poor prognosis.

Observation:

  • A 5-year-old boy presented with localized pain and was diagnosed with a hyperintense, lobulated lesion spanning D1-D4 with significant intraspinal and thoracic components.
  • Surgical intervention involved a dorsal laminectomy and right posterolateral thoracotomy, achieving complete tumor resection.

Findings:

  • Pathological examination confirmed the diagnosis of PNET.
  • Postoperative recovery was uneventful, with no neurological deficits. A six-month follow-up MRI revealed no evidence of tumor recurrence.

  • This case is unique as it involves a thoracic, extradural PNET, with the patient remaining disease-free at 8 months post-surgery.

    • Implications:

    • The successful management of this rare extradural spinal PNET highlights the potential for complete resection in select cases.
    • Further research into novel treatment strategies is crucial to enhance survival rates for primary intraspinal PNETs.
    • This case contributes valuable data to the limited literature on pediatric intraspinal PNETs, emphasizing the need for tailored therapeutic approaches.
