Abstract Introduction: Benign Paroxysmal Positional Vertigo is the most common type of vertigo in adults. In the literature we found the coexistence of BPPV with other ear pathologies and the most commonly recognized conditions are head trauma and infections.Methods: This report of a 51 years old man diagnosed before with neurocysticercosis summerise a possible association between otosclerosis and BPPV. Otosclerosis is a progressive disease that affects middle and inner ear; it has been associated with an increase incidence of vestibular symptoms but in its vestibular McCabe form. BPPV is a mechanical peripheral vestibular disorder, idiopathic or secondary. The most commonly recognized conditions are head trauma or infections, Meniere’s disease and post-surgery.Secondary BPPV is often underdiagnosed because dizziness is usually attributed to the primary inner ear pathology.Results: The complete neurootological and audiological evaluation were performed; we recognized the associated pathology (otosclerosis left ear and BPPV-left posterior semi-circular canal).The positional vertigo developed after two years of conductive hearing loss, but in the same time(aprox two weeks) with ipsilateral tinnitus. Usually, recurrence is present more in secondary BPPV than in idiopathic cases but in this situation the canalith repositioning maneuver Epley was immediately successful.Conclusion: Unfortunately, the clinical differences between idiopathic and secondary BPPV are limited. This clinical case suggest that otosclerosis could be an underlying condition for BPPV. A search of the literature reveals that neurocysticercosis as a trigger factor for BPPV represents a unique case.Keywords: BPPV, otosclerosis, neurocysticercosis.Der Erstautor gibt keinen Interessenkonflikt an.
