Pure posterior chordoid foramen magnum meningioma: A case report and review of literature

Ali Hammed et al. Ann Med Surg (Lond). .

Abstract

Introduction and importance: Meningiomas are extra-axial central nervous system (CNS) tumors that arise from the arachnoid cells of the dura mater. Only 1.8-3.2% of all meningiomas are located at foramen magnum (FM) and pure posterior FM meningioma are very rare. The diagnosis of malignancy in patients with meningiomas has been a controversial issue. Only a histological study can confirm this situation.

Case presentation: We report a case of A 52-year-old female presented with a history of neck pain with progressive spastic quadriparesis.

Clinical discussion: Magnetic resonance imaging MRI T1 and T2 weighted images revealed well-defied pure posterior foramen magnum Lesion. Although the lesion was very sticky to neurovascular components. Simpson grade I was achieved. Histopathology revealed Chordoid meningioma. The patient had a dramatic recovery.

Conclusion: Although choroid meningioma is usually well circumscribed, sticky tumors should be suspected. Recurrence of Chordoid meningioma should be suspected. Total excision should be achieved and routine follow-up should be informed. Reports about chordoid meningioma aren't common, but reports on choroid foramen magnum meningioma are very rare. The opportunity to give the patient a symptom-free and normal life should not be missed in such cases.

Keywords: Chordoid meningioma; Foramen magnum meningioma (FMM); Pure posterior FMM.
