Pineoblastomas, rare brain tumors, can metastasize to the spine years after initial surgery. While one patient achieved remission with chemotherapy and stem cell transplant, another succumbed to spinal seeding despite aggressive treatment.

Area of Science:

  • Neuro-oncology
  • Neurosurgery
  • Medical oncology

Background:

  • Pineoblastomas are rare, aggressive embryonal neuroepithelial tumors of the central nervous system (CNS).
  • Extraneural metastases from CNS tumors are uncommon, particularly from pineoblastomas.
  • Vertebral involvement represents a rare but serious complication of pineoblastoma progression.

Observation:

  • Two male patients, aged 26 and 18 years, presented with vertebral metastases from pineoblastomas previously treated with surgery.
  • The first patient developed a T8 vertebral metastasis 8 years post-surgery, while the second had a sacral metastasis 5 months post-surgery.
  • These cases highlight the potential for late extraneural recurrence in pineoblastoma survivors.

Findings:

  • The patient with T8 vertebral metastasis achieved disease control following high-dose chemotherapy and autologous blood stem cell transplantation.

  • The patient with sacral metastasis experienced rapid disease progression and died from spinal seeding despite aggressive adjuvant therapy.
  • Treatment outcomes for vertebral pineoblastoma metastases are variable, influenced by tumor burden and therapeutic interventions.

    • Implications:

    • These cases underscore the importance of long-term surveillance for extraneural metastases in pineoblastoma patients.
    • The findings suggest that aggressive multimodal therapy, including chemotherapy and stem cell transplantation, may be effective in managing vertebral pineoblastoma metastases.
    • Further research is warranted to elucidate the mechanisms of extraneural spread and to optimize treatment strategies for these rare occurrences.
