Primary meningioma of the nasopharynx: case report and review of ectopic meningioma.
Meningiomas not uncommonly spread outside the central nervous system, but primary extracranial meningiomas are much less common, the sites described including the orbit, the calvarium, the neck, the temporal bone and the paranasal sinuses. Reported here is the first instance of extracranial meningioma of the nasopharynx. The histological appearance of meningiomas is diverse, and in ectopic sites can be mistaken for malignant epithelial tumors, as happened here initially. The tumor was excised via a transpalatal flap using an intracapsular debulking approach borrowed from the armamentarium of the intracranial surgeon. Prolonged follow-up with interval CT scans are recommended in patients with apparent ectopic meningioma, in case undemonstrable intracranial disease later becomes manifest.
