Abstract

This case demonstrates the successful identification and treatment of atypical posterior semicircular canal benign paroxysmal positional vertigo (BPPV) based on a unique presentation of positional nystagmus, the resultant nystagmus from repositioning manoeuvers, and restored function of the affected semicircular canal. This case illustrates the importance of completing a comprehensive clinical examination and the value for incorporating the video head impulse test as well as adjusting treatment based on testing and patient response when managing variant cases of BPPV.
