title: The vestibulocochlear nerve.
abstract: The eighth nerve provides sensory connection for balance and sound. Our ability to evaluate its morphology and pathology with magnetic resonance imaging (MRI) has been substantially improved over the past 20 years. This article reviews the relevant anatomy of the eighth nerve. A thorough discussion of the potential pathologic processes affecting its function also is included. Foremost, is a review of acoustic schwannomas, emphasizing the role of imaging in the work-up and ongoing evaluation of these patients. Discussion and examples of the plethora of neoplastic, inflammatory, infectious, congenital, ischemic, and compressive pathologies involving the nerve are included as well.
