Lateral medullary syndrome

Short Description or Definition

Described in 1895 by Wallenberg and later outlined by Fisher et al. (1961), this syndrome is produced by a lesion in a wedge of lateral medulla lying posterior to the inferior olivary nucleus. It is frequently the result of an infarction, and however, although much rarer, may also be due to a small well-localized hemorrhage or a tumor. The complete syndrome involves the vestibular nuclei, spinothalamic tract, descending sympathetic tract, fascicles of the ninth and tenth nerves, otolithic nucleus, olivocerebellar and/or spinocerebellar fibers, and restiform body. The symptoms most frequently associated with this syndrome are ataxia (84%), numbness (78%), dysphagia (69%), vertigo (60%), nausea (58%), dysarthria (49%), headache (44%), as well as hoarseness, facial pain, hiccups, and others. Long-term disability affecting multiple domains can result from this strategically localized infarction.
