title: [Non-benign paroxysmal positional vertigo].
abstract: Positional vertigo is a frequent clinical manifestation of vertigo of very different etiologies, being the benign paroxystic positional vertigo (BPPV) the most frequent one of them, representing in some series even the most found etiology of peripheral vertigo. Usually of severe entities, positional vertigo may appear in the context of severe entities and of difficult diagnosis. In these cases, the bearing of the symptoms in spite of the repositioning manoeuvers, the association with otological or neurological symptoms, and the atypical nystagmus evoked by Dix-Hallpike manoeuver, must take the otolaryngologist to suspect of a feasible non benign pathology. We report a case of positional paroxysmal vertigo caused by an intracranial tumour and we review the clinical signs that shoved help us to suspect of non benign pathologies that can mimic a positional vertigo.
