title: Understanding the posttreatment imaging appearance of the internal auditory canal and cerebellopontine angle.
abstract: The intent of this article is to become familiar with the post-treatment appearance of the cerebellopontine angle (CPA) and internal auditory canal (IAC). This includes a review of the pertinent pathology, surgical approaches, and post-treatment imaging appearance. A post-treatment imaging algorithm is suggested.
