- For differential diagnosis between vestibular neuritis and lateral medullary
infarction with similar clinical features, bedside examination of nystagmus is
important. We report a 45-year-old male who presented with acute vertigo for
two days. He showed spontaneous right-beating nystagmus. However, left-beating
nystagmus was evoked during bilateral horizontal gaze and by horizontal head
oscillation. Brain MRI revealed an acute infarction in the left lateral medulla.
