This study details a rare chordoid meningioma case unrelated to Castleman syndrome. The patient experienced epilepsy and hemiparesis, with successful tumor resection and symptom resolution.

Area of Science:

  • Neurology
  • Pathology
  • Oncology

Background:

  • Chordoid meningioma is a rare meningioma variant.
  • It is frequently associated with Castleman syndrome (CS).

Observation:

  • A 44-year-old woman presented with epilepsy and right hemiparesis.
  • Radiology showed an extraaxial premotor cortex mass, consistent with meningioma.
  • No CS-related physical findings were present.

Findings:

  • Surgical resection (Simpson grade I) was successful with an uneventful recovery.
  • Pathology confirmed chordoid meningioma, characterized by spindle and epithelioid cells in a myxoid matrix.
  • Immunohistochemical and electron microscopic analyses supported the diagnosis.

Implications:

  • This case highlights a chordoid meningioma presentation not associated with Castleman syndrome.
  • It underscores the importance of differential diagnosis in brain tumors presenting with neurological deficits.
  • Further research into rare meningioma variants and their associations is warranted.
