Summary
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.
