Although benign paroxysmal positional vertigo and endolymphatic hydrops are considered to be distinct diagnoses, a minority of vertiginous patients exhibit features of both conditions. This coincidence has been reported previously in the literature, and is reviewed here in terms of possible aetiology.
A new hypothesis to account for both conditions is offered, implicating free-floating degenerating debris from the otolithic apparatus. It is postulated that the gelatinous/proteinaceous component may account for an osmotically induced hydrops, while the calcified fragments may induce positional vertigo.
