LATRAL MEDULLARY SYNDROME :
Cerebellar signs, contralateral sensory loss & ipsilateral Horner's
Lateral medullary syndrome, also known as Wallenberg's syndrome, occurs following occlusion of the posterior inferior cerebellar artery PICA.
-Cerebellar features:
ataxia
nystagmus
-Brainstem features:
ipsilateral: dysphagia, facial numbness, cranial nerve palsy e.g. Horner's
contralateral: limb sensory loss.
