Abstract
PDF - Case history of a 67-year-old man diagnosed with posterior benign paroxysmal positional vertigo (BPPV) with extremely long latencies after holding the Dix-Hallpike position for five minutes. Additional vestibular assessment indicated partial unilateral hypofunction. The patient had a history compatible with classic BPPV. This patient, however, did not have any positional nystagmus after doing standard positional testing. With extremely prolonged Dix-Hallpike testing (five minutes), the patient experienced nausea and vertigo. Concomitantly classic peripheral nystagmus was observed. After a total of seventeen treatments in a reposition chair a total relief of symptoms was obtained. The extremely long latencies observed in this patient were ascribed to otoconial adherence and/or otoconial size. This type of BPPV has not previously been described.
