Abstract

Lateral medullary syndrome, also known as Wallenberg syndrome, is characterized by sensory deficits affecting the trunk and extremities on the opposite side of the lesion, and the face and cranial nerves on the same side of the lesion. Other clinical symptoms and findings are dysphagia, slurred speech, ataxia, facial pain, vertigo with nystagmus, Horner's syndrome, diplopia, and possibly palatal myoclonus. The cause of this syndrome is usually occlusion of the posterior inferior cerebellar artery or vertebrobasillar artery. We observed a case of Wallenberg syndrome occuring secondary to the cavernous malformation and initially presenting as unilateral vocal cord palsy. The centrally-medicated vocal cord palsy is a rare cause of hoarseness, but should be considered in cases where no other local cause can be found.
