Spinothalamic tract: loss of pain and temperature sensation to the opposite side of the body.

Trigeminal nucleus: ipsilateral facial and corneal anesthesia.

Nucleus ambiguous: dysphagia, dysphonia, and dysarthria, laryngeal, pharyngeal and palatal paralysis.

Involvement of various structures in lateral medulla along with respective manifestation or clinical signs include

An abnormality of the intima and vascular wall.

VirchowвЂ™s triad play an important role in understanding the pathogenesis of Wallenberg's syndrome.

Dissection and increased vascular tortuosity.

Athero-embolic phenomenon (heart, aorta, or vertebral arteries).

The various pathophysiologic mechanisms involved can include The lateral medullary syndrome is basically a manifestation of the vaso-occlusive disease of intracranial vertebral arteries (ICVA) such as vertebral artery or posterior inferior cerebellar artery.

Vertebral Basal Insufficiency (VBI) was first introduced by clinicians at the Mayo Clinic, Bob Siekert and Clark Millikan in 1970s.

Charles Foix (1882вЂ“1927) was the first person to write an extensive case series on posterior cerebral arteries occlusion related syndromes and lateral medullary syndrome.

Joseph Jules Dejerine (1849вЂ“1917) and his wife Dejerine-Klumpke demonstrated extensive visual illustrations of the various brain stem and cerebellar lesions.

He performed necropsies and extensive dissections on his patient's brains.

Thomas William was the first person to document extensive anatomy and physiology of brain stem, the cerebellum, and the ventricles in the 17th century.

This syndrome was later on further elaborated by Adolf Wallenberg, in 1895.

Gaspard Vieusseux, in 1808, was the first person to describe Wallenberg's syndrome.

The various pathophysiologic mechanisms involved can include atherosclerosis, athero-embolic phenomenon (heart, aorta, or vertebral arteries), dissection and increased vascular tortuosity, vascular insufficiency, VirchowвЂ™s triad play an important role in understanding the pathogenesis of Wallenberg's syndrome. The most common cause is thromboembolic occlusion of vertebral arteries. It is also commonly known as Wallenberg's syndrome or posterior inferior cerebellar artery syndrome (PICA). The lateral medullary syndrome is one of the most common clinical syndromes of brain stem caused by the decreased blood supply to the lateral medulla.
