영문 초록

Facial nerve schwannomas in the internal auditory canal and cerebello-pontine angle are rare benign tumors which are difficult to diagnose due to their various clinical symptoms and magnetic resonance imaging(MRI) findings show similar findings compare to th vestibular nerve schwannomas. Therefore, the enhancement pattern of facial nerve in MRI is the clue to predict the origin of the tumor. We experienced a case of senosorineral hearing impairment with history of intermittent dizziness and Bell s palsy in the right side before 15 years ago. Temporal bone MRI finding showed facial nerve enhancement in the tympanic segment, geniculate ganglion, and GSPN in T1-weighted enhancement images. At first, we thought of it as a facial nerve schwannoma due to the facial nerve enhancement pattern but it was proven to be a vestibular nerve schwannoma in the operation field.
