 Whether you're a neuroradiologist or a general radiologist or wherever you practice you're going to be evaluating patients with hearing loss, with dizziness and with vertigo. And the majority of the times the patient get brain MRs and brain CTs which we're all going to be aware of. And typically we tend to focus on the causes being centrally within the brain. But eventually you're going to have various pathologies that can cause these symptoms. And we as radiologists that are charged with evaluating the brain and we perform MR are going to have to be familiar with not only the central causes within the brain but also the cerebellar-pontine angle. So when we have the cerebellar-pontine angle we're responsible for the anatomy for the imaging technique and accurately diagnosing the various pathologies that can occur in this important area.
