title: Geniculate neuralgia and audio-vestibular disturbances due to compression of the intermediate and eighth nerves by the postero-inferior cerebellar artery.
abstract: A compression of the intermediate, cochlear and vestibular parts of the VIII nerve by a redundant loop of the posterior inferior cerebellar artery (PICA) was found at autopsy in a patient who suffered during 21 years of geniculate neuralgia associated with tinnitus, hypoacousia and occasional dizziness. The relationship of arterial cross compression to geniculate neuralgia and audio-vestibular disturbance is discussed.
