Insights

Rhabdoid meningioma, a rare tumor variant, can occur in recurrences. This case presents the first reported instance of intraventricular rhabdoid meningioma following a fibroblastic meningioma.

Area of Science:

  • Neuro-oncology
  • Pathology
  • Neurosurgery

Background:

  • Meningiomas are tumors arising from the meninges.
  • Rhabdoid meningioma is an aggressive, rare variant.
  • Intraventricular meningiomas occur within the brain's ventricles.

Observation:

  • A 55-year-old woman presented with headache and tinnitus 5 years post-resection of an intraventricular fibroblastic meningioma.
  • Imaging revealed a recurrent intraventricular tumor.
  • Histological examination confirmed the presence of rhabdoid meningioma.

Findings:

  • This represents the first documented case of intraventricular rhabdoid meningioma.
  • The tumor recurred as a different histological subtype.

Implications:

  • Highlights the potential for meningioma recurrence with varying histology.
  • Suggests the need for vigilance in monitoring intraventricular meningioma survivors.
  • May inform future diagnostic and treatment strategies for rare meningioma variants.
