中文摘要 | 頭頸部之神經鞘瘤常見於內耳道和小腦橋腦角。而同時分別出現於迷路內及內聽 道者,則較為少見。本科曾經驗一55歲女性病患,因右耳耳鳴及聽力障礙求診,結果在核磁 共振造影術下發現,右側迷路內及內聽道內同時存在兩個狀似完全分開之腫瘤。分二次以迷 路切除術切除右側迷路內腫瘤及經迷路路徑方式切除內聽道腫瘤,結果病理報告指出,此二 移除物皆為神經鞘瘤。術後追蹤至今,並無併發症之產生。 |
英文摘要 | Acoustic schwannoma is an unusual benign tumor, which occurs in the internal auditory canal and/or cerebellopontine angle more commonly than being limited to the labyrinth. It is relatively rare to find such an isolated tumor in both the labyrinth and the internal auditory canal. A 55 year-old woman came to our clinic with the chief complaints of tinnitus and hearing limpairment in her right ear for one year. No history of head injury or mumps was reported. An audiogram showed a total hearing loss in the right ear and magnetic resonance images revealed two tumor masses located separately in the right labyrinth and the right internal auditory canal. A transmastoid labyrinthectomy and a translabyrinthine approach surgery, were performed to remove the soft, pink lobulated tumors. The pathological report indicated these two masses were schwannomas. The patient was discharged uneventfully and has been free of symptoms to date. |
