Abstract

Periodic alternating nystagmus (PAN) is a spontaneous horizontal jerky nystagmus that reverses its direction periodically with a quiescent interval. PAN has been reported in acquired and congenital forms. The main lesion site of the acquired form of PAN has been attributed to the caudal brainstem or cerebellum. Herein we report a 63-year-old male patient with Meniere's disease, who presented PAN during a vertigo attack. The patient demonstrated no abnormality on neurologic evaluation and brain imaging, which is different feature compared to the central or congenital form of PAN. It should be kept in mind that peripheral vestibular disorders such as Meniere's disease can produce PAN.
