lateral medullary syndrome

A

Lateral medullary infarction (Wallenberg syndrome) may present with a constellation of symptoms, including vertigo. Some refer to an ischemic event in this territory with clinical findings as posterior inferior cerebellar artery syndrome. The classic features of this syndrome include ipsilateral cranial nerve deficits (e.g., Horner syndrome, soft palate paralysis) and contralateral deficits in the trunk and extremities (e.g., loss of pain and temperature sensation). This crossed pattern of deficits is a hallmark of the diagnosis.
