title: Benign paroxysmal positional vertigo after decompression sickness: a first case report and review of the literature.
abstract: Benign paroxysmal positional vertigo is a common cause of vertigo. We describe a previously unreported case of this clinical entity in a young, fit recreational water diver, having experienced decompression illness. Full recovery occurred after hyperbaric recompression therapy, and he remained symptom free on 6-week follow-up. We review the literature and discuss the pathogenesis of benign paroxysmal positional vertigo, proposing that semicircular canal nitrogen bubble formation could have been the primary etiological event leading to this condition.
