摘要：
A case is presented of an entirely intracanalicular meningioma in a 48-year-old woman that was excised via a conventional translabyrinthine approach to the internal auditory canal (IAC). Pre-operative magnetic resonance imaging (MRI) suggested that the tumour was a vestibular schwannoma (VS). Histological examination confirmed the intra-operative impression that the tumour was a meningioma. Although VS is by far the commonest intracanalicular tumour, the differential diagnosis includes meningioma. MRI is unable to distinguish between these two entities when the tumour is located entirely in the internal auditory canal.
