Wallenberg’s syndrome also known as lateral medullary syndrome is one of
the most commonly recognized conditions resulting from the brainstem
infarction. In some cases the posterior inferior cerebellar artery may
also be occluded at the orifice.
It does not produce weakness: consequently, stoke may not be considered on initial evaluation.
Despite the higher prevalence of Wallenberg’s syndrome due to
cerebrovascular accident, cases of symptom emergence resulting from
brain tumor have also been reported.
Wallenberg’s syndrome manifests in a collection of symptoms including
vertigo and dizziness, cerebellar gait ataxia, dysphagia, dysphonia and
Horner’s syndrome.
Occasionally, patients with Wallenberg’s syndrome develop diplopia due
to skew deviation. Hiccups and 90-180 degree tilt of the perceived world
can occur.
