Abstract
Imaging of the cerebellopontine angle and internal auditory canal has become one of the cornerstones of modern head and neck imaging. Due to advances in imaging techniques with newer magnetic resonance (MR) sequences using thinner slice thickness and a higher resolution, the scala of detectable pathologies has increased tremendously. In this chapter, the lesions in and around the cerebellopontine angle cistern (CPA) are discussed, trying to emphasize some characteristic imaging features of most lesions. After illustrating the imaging protocol and imaging anatomy, pathological entities in this chapter will be discussed upon origin and/or location.
