[Diagnostic imaging of peripheral vertigo].

Clinical imaging investigation of vertigo is actually mainly performed using MRI, which offers a detailed analysis of cochieo-vestibular nerve and labyrinth. Computed tomography is reserved to the analysis of bony structures. Several causes of vertigo are described, e.g. tumours, labyrinthitis, malformations, Ménière's disease, otoscierosis, trauma, cholesteatomas and postoperative changes. The interest of imaging is discussed. The necessity to perform paraclinical tests prior to diagnostic imaging to optimise the choice of imaging is emphasized.
