Named after Adolf Wallenberg in 1895, this neurological condition is characterized by lateral medullary infarction resulting from an occlusion of the posterior. There are prominent neuro-ophthalmic findings in a patient with Wallenberg syndrome and is usually caused by compromise of the posterior inferior cerebellar artery (PICA) leading to infarction. Spinal nucleus of trigeminal nerve damage: Ipsilateral loss of pain and temperature sensation.
Spinothalamic tract damage: Contralateral loss of pain, temperature and crude touch from upper and lower limbs and trunks. (Wallenbergs Syndrome) causes the person to have balance problems and lean to one side. Dys diadochokinesia Irregular performance of rapid alternating movements. The structures affected by the infarction in the lateral medulla include the vestibular nuclei, inferior cerebellar peduncle, descending sympathetic pathways, and lateral spinothalamic tract (Figure 5). Artery (PICA) carries blood to this part of the brain. Axial MRI of the brain showed a hyperintensity on DWI in the right lateral medulla and a corresponding hypointensity on the ADC map consistent with an acute infarction of the right lateral medulla (Figure 4). Dilated fundus examination revealed excyclotorsion of the right eye and incyclotorsion of the left eye (Figure 3). Wallenberg syndrome (WS) is a neurological disorder that is due to damage to the lateral portion of the medulla oblongata (i.e., the lateral medullary syndrome). The syndrome is occasioned by occlusion of the PICA ostium (usually by thromboembolus lodging in. the lateral medullary syndrome, is a clinical testament to PICA association with the lateral spinal artery. The clinical syndrome of PICA occlusion (Wallenberg and its various partial forms), a.k.a. The patient's eyes were deviated to the right during eyelid closure, demonstrating ocular lateropulsion (Video 1). PICA occlusion and the lateral medullary syndrome. He had gaze-evoked nystagmus only on right gaze, hypermetric saccades to the right, hypometric saccades to the left, and a left hypertropia that improved with right head tilt and worsened with left head tilt. Wallenberg syndrome is a condition that affects the nervous system.Signs and symptoms may include swallowing difficulties, dizziness, hoarseness, nausea and vomiting, nystagmus, and problems with balance. External examination showed right ptosis and miosis indicating a right Horner syndrome (Figure 1).
