Vertigo, Nausea, Vomiting and Nystagmus.Analgesia and Thermaesthesia on the Ispsilateral side of the face ( Due to lesion of Nucleus and Spinal tract of Trigeminal nerve).Dysphagia and Dysarthria ( Due to paralysis of Ipsilateral palatal and laryngeal muscles- Innervated by Nucleus Ambiguus).He has a medical history of atrial fibrillation, hypertension, hyperlipidemia, and type 2 diabetes mellitus. He was last known to be neurologically normal 2 hours prior to presentation. Lateral Medullary syndrome of Wallenberg Signs and Symptoms that are Characteristic of Wallenberg Syndrome are- A 55-year-old man presents to the emergency department for difficulty with speech and weakness in the right upper extremity. The most commonly affected artery is the vertebral artery, followed by the PICA, superior middle and inferior medullary arteries. Causing lateral part of the medulla oblongata to infarct.It is concluded that rostrocaudal and horizontal classification of MRI helps us to understand the clinical and, partly, the aetiopathogenetic aspect of the heterogeneous LMI syndrome. It is caused most commonly due to atherothrombotic vertebral artery occlusion, followed by posterior inferior cerebellar artery (PICA) and medullary arteries. It results from thrombosis of Posterior Inferior Cerebellar Artery. Patients with isolated PICA disease (versus those with VA disease) more often had cardiogenic embolism (P It supplies the posterior part of inferior surface of Vermis, Central nucleii of Cerebellum and undersurface of Cerebellar hemisphere.It also supplies Medulla ( branches of PICA along with medullary branches of Vertebral artery) and Choroid Plexus of 4 th ventricle.Īdolf Wallenberg (November 10, 1862-1949) ,a German internist and neurologist, first described the clinical manifestations (1895) and the autopsy findings (1901) in occlusions of the arteria cerebelli posterior inferior (Wallenberg syndrome) Cause :. It is one of the 3 major arteries supplying the cerebellum. An estimated 60,000 new cases occur each. The posterior inferior cerebellar artery also known as PICA is the largest branch of the vertebral artery, passes on an irregular course between Medulla and Cerebellum. Wallenberg syndrome is a neurological condition that is also referred to as lateral medullary syndrome or posterior inferior cerebellar artery syndrome.
