摘要

顱外腦膜瘤是相當少見且不易診斷的。發生的部位多集中在頭皮、眼窩、鼻腔或副鼻竇。台大醫院耳鼻喉科經驗一罕見之側咽腦膜瘤，其臨床表現為持續性輕度發燒及咽部不適；患者並有漸進性之右側聽力障礙。電腦斷層掃描發現該腫瘤佔據右側側咽間隙、右頸靜脈孔以及右小腦橋腦角。經口內切開式活體切片後證實為侵襲性腦膜瘤。經施予放射線治療而症狀緩。因顱外腦膜瘤很少發生於此區，特提出報告，並探討其發生的機轉。

A 76-year-old woman with an unusual invasive meningioma growing in the parapharyngeal space is presented. It was manifested by progressive right hearing loss, mild fever and swelling of the right parapharynx. The computerized tomograpgy showed a right parapharyngeal mass and a right cerebellopontine angle mass with connection through the jugular foramen. The parapharyngeal mass was biopsied and the pathology revealed invasive meningioma. Extracranial meningioma may occur is some occasions, but rarely reported in the parapharyngeal space though it is in the vicinity of base of the skull, In this case, the tumor might arise from the right cerebellopontine angle and it extended extracranially through the jugular foramen to the parapharyngeal space, where it was found by clinical examination.
