Figure 1 General Epidemiology. [1] In humans, the cerebellum plays an important role in motor control. tremors. Frontal eye fields: gaze deviation toward the affected side and away from the side of hemiplegia Answer: Lateral medullary syndrome (also known as Wallenberg syndrome, posterior inferior cerebellar artery ( PICA) syndrome, and vertebral artery syndrome) is a neurological constellation of symptoms and signs due to obstruction in vessels supplying the medulla, resulting in brainstem ischemia or infarction. 2012; Suzuki and Izumi 2013), each of which can have effects on brain structure independent of alcohol or each other. A case of medial inferior pontine syndrome or Foville's syndrome is described. Lateral medullary syndrome (also called Wallenberg syndrome and posterior inferior cerebellar artery syndrome) is a disorder in which the patient has a constellation of neurologic symptoms due to injury to the lateral part of the medulla in the brain, resulting in tissue ischemia and necrosis..

These initial symptoms include: Muscle weakness in your limbs Palsies tremors and paralysis Difficulty speaking Difficulty swallowing Changes in consciousness Coma Death Originally, inferior medial pontine syndrome (Foville syndrome) Due to occlusion of basilar perforators (paramedian branches). The medicinal application of opioids can be dated back to 1500 B.C. Vertebrobasilar insufficiency (VBI) describes a temporary set of symptoms due to decreased blood flow in the posterior circulation of the brain.The posterior circulation supplies the medulla, pons, midbrain, cerebellum and (in 70-80% of people) supplies the posterior cerebellar artery to the thalamus and occipital cortex. Medial lemniscus is also affected, but not pictured.) The symptoms include sudden onset The neurologic exam revealed that the limbs on the right side had markedly diminished strength, heightened deep tendon reflexes, ankle clonus, (Medial pontine syndrome affects structures at the bottom of the diagram: the corticospinal tract, abducens nerve, and occasionally the facial nerve. swallowing difficulties. These findings suggest a unique pontine stroke 2011), and stroke (de los Rios et al. However, when a stroke affects the pons, it can result in muscle weakness in the face, arms, and legs. Last Updated on Wed, 11 May 2022 | Anatomy. Accurate diagnosis and appropriate plans of management can be achieved with careful history taking and clinical examination. We coined the term "pontine warning syndrome" to characterize recurrent stereotyped episodes of motor or sensory dysfunction, dysarthria, or ophthalmoplegia associated with a high risk of imminent basilar artery branch infarction and a permanent deficit resembling those of capsular warning syndrome.

As a result, symptoms vary widely depending which brain region Medial pontine syndrome; Pons. Medial lemniscus is also affected, but not pictured.) Many of the symptoms of cerebellar infarction are non-specific, such as nausea, vomiting, dizziness, unsteadiness and headache, and the clinical diagnosis relies on focused neurological examination and a reasonable index of suspicion. The cerebellum (Latin for "little brain") is a major feature of the hindbrain of all vertebrates. Diffusion-weighted magnetic resonance imaging revealed a punctate area of acute ischemia in the right medial pontine mid-tegmentum. Focal Generalised Status epilepticus Myoclonic epilepsy. Pons is the largest component of the brainstem located distal to the midbrain and proximal to the medulla oblongata. Occlusion of AICA results in lateral pontine syndrome (Marie-Foix syndrome), also known as AICA syndrome. What CNS structures are affected? This leads to poor oxygen supply or cerebral hypoxia and thus leads to the death of brain tissue or cerebral infarction/ischemic stroke. Localization: Infarction of the ventral posterior lateral (VPL) and ventral medial nuclei (VPM), supplied by thalamoperforators from the posterior cerebral artery.
