Meningiomas rarely spread outside the brain. This study details an unusual case of recurrent thoracic metastasis from a benign intracranial meningioma, successfully treated with surgery.

Area of Science:

  • Neurosurgery
  • Oncology
  • Pathology

Background:

  • Meningiomas are common primary central nervous system tumors, typically benign.
  • Metastasis outside the intracranial compartment is rare for meningiomas.
  • Predicting aggressive behavior and metastasis remains challenging.

Observation:

  • A patient with a history of intracranial benign meningioma developed recurrent thoracic metastases.
  • The metastasis occurred after an 8-year disease-free interval.
  • The patient had a benign intracranial meningioma.

Findings:

  • Histological tumor grade is a key predictor of meningioma recurrence and metastasis.
  • This case highlights the potential for late, extrapleural metastasis from benign meningiomas.

  • Wide surgical excision of the metastasis led to a successful outcome.

    • Implications:

    • This case expands the understanding of meningioma metastatic potential.
    • It underscores the importance of long-term surveillance for patients with meningiomas.
    • Further research may identify criteria for predicting aggressive meningioma behavior.
