 In this case, there was no difference of pure-tone audiometry between the right and left ears. A auditory brainstem response and caloric test showed no abnormal findings. On the other hand, an eye-tracking test and the optokinetic nystagmus test revealed abnormal findings. From the nystagmus findings, right posterior canal type BPPV was the most likely, so the Epley maneuver was performed three times daily. However, there was no improvement. It was believed that the cases that are most likely to be BPPV from the symptoms and nystagmus findings, the neuro-otological testing should be performed, and if any abnormalities were observed or if it was refractory with the canalith repositioning procedure, MRI imaging should be performed.
