Abstract

Bruns' nystagmus occurs with cerebellopontine angle tumors, associated with cranial nerves or brainstem dysfunction. Many CN waveforms are attributed to an instability of the smooth pursuit system. We report a unique case of CN clinically resembling Bruns' nystagmus, indicating that EM recording should always be done when nystagmus occurs without oscillopsia, even with associated brainstem signs. We also hypothesize that different instability mechanisms are sometimes dominant in each eye, causing different CN waveforms, and other times the same mechanism is dominant in both, causing the same waveforms.
