  • Title: [Vertigo and pathology of the cerebello-pontine angle].
    Author: Franco-Vidal V, Négrevergne M, Darrouzet V.

    Abstract:
    Many pathologies of the cerebello-pontine angle can induce vertigo or dizziness. Usually they are due to benign or malignant tumors. Pathophysiology of this vertigo involve lesion of the labyrinth with erosion, of the endolymphatic sac by invasion or compression, or directly by lesion of the vestibular nerve like in vestibular schwannomas. The vestibular nerve can also be injured by extrinsic compression like in meningiomas. Finally very big tumors can be compressive on the cerebellum or on the brainstem inducing also dizziness. Vertigo is often an important symptom of cerebello-pontine angle tumors. In association with others it will guide the diagnosis. Nevertheless, auditory evoked potentials, video-nystagmography, and otolithic evoked potentials are very important to determine exactly if the vestibular nerve is injured and if there are signs of central compression before surgery.
