Abstract

Objective: Case history of a 67-year-old man diagnosed with posterior benign paroxysmal positional vertigo with extremely long latencies after holding the Dix-Hallpike position for five minutes. Additional vestibular assessment indicated partial unilateral hypofunction.
Methods
Case report
Results
Patient 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.
Conclusions
Patient history compatible with BPPV. 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.
