This from Kanel, Schwartz, Jessell, 3rd ed page 728:
The lateral medullary syndrome (Wallenberg syndrome) is caused by an
infarction in the distribution of the posterior inferior cerebellar
artery. Oftern, however, the actual occlusion is found in the parent
vessel, the vertebral artery. The damaged area includes the dorsal
portion of the lateral medulla, the lateral medullary tegmentum. In
addition to the six common characterists [1.contralateral loss of pain
and temperature sensation of the libms and trunk due to damage in the
spinothalamic tract; 2ipsilateral Hornersyndrome with miosis (small pupil
with normal reaction to light),ptosis of the eyelid, and decreased
sweating on the ipsilateral side of the face due to interruption of
descending autonomic fibers;3ipsilateral loss of cutaneous sensation on
the face from involvement of the sensory trigeminal nucleus ro descending
tract;4nystagmus and nausea attributed to involvement of vestibular
connections;5ataxia of the ipsilateral limbs due to interruption of
cerebellar connections (the restform body in the medulla, and the middle
and superior peduncles in the pons);and for reasons not known 6hiccup.]
glossopharyngeal (IX) and vagal(X) nerves may e involved, causing
difficulty in swallowing (dysphagia), hoarseness of the voice because of
paralysis of the ipsilateral vocal cord, and loss of taste on the
ipsilateral half of the tongue.
