Lateral medullary syndrome is a neurological disorder causing a range of symptoms due to ischemia in the lateral part of the medulla oblongata in the brainstem
  2. Our case series highlights two major patterns of pontine infarcts that resulted in peripheral-type facial weakness. The lateral pontine lesion is mainly found in type A, which involves the pontine circumferential vessel or anterior inferior cerebellar artery territory, and sometimes shows multi-vessel involvement (Cases A-1 and A-2)
  3. Treatment. The pons is a region of the brain located in the brainstem. The pons is relatively small, and it is located in the lower part of the brain, connecting the cerebral cortex with the medulla oblongata . The pons contains nerves and nerve tracts (pathways) that integrate brain functions such as movement and sensory messages between the.

Left sided cerebellar stroke due to occlusion of a vertebral artery. Cerebellar stroke syndrome is a condition in which the circulation to the cerebellum is impaired due to a lesion of the superior cerebellar artery, anterior inferior cerebellar artery or the posterior inferior cerebellar artery.. Cardinal signs include vertigo, headache, vomiting, and ataxia More severe brain stem strokes can cause locked-in syndrome, a condition in which survivors can move only their eyes. If a stroke in the brain stem results from a clot, the faster blood flow can be restored, the better the chances for recovery. Patients should receive treatment as soon as possible for the best recovery

As the cerebellum is perfused by, inter alia , the PICA, interruption of the vascular supply in Wallenberg Syndrome can also often result in some degree of cerebellar. Site of the lesion: The findings indicate a lesion affecting the right lateral pons with evidence of spinocerebellar involvement. In this case the lesion was not vascular in origin but in fact an example of a cerebellopontine angle lesion - an acoustic neuroma (or schwannoma) Lesions in this area can cause Foville's syndrome (damage to the pontine tegmentum) which is classified by partial sixth nerve palsy, ipsilateral facial weakness, loss of taste in the anterior portion of the tongue, ipsilateral Horner's syndrome, ipsilateral facial sensory loss and ipsilateral peripheral deafness

Pontine stroke is a type of stroke that happens when the blood flow in the brain stem is disrupted. The brain stem is responsible for breathing, heart function, digestion and alertness. Pontine stroke is very dangerous.

Mills' syndrome, which was first described by Mills in 1900, is a rare clinical syndrome characterized by progressive ascending or descending hemiplegia without significant sensory involvement [].Although Mills suggested that this disorder was caused by primary degeneration of corticospinal tract unilaterally, secondary causes could not be eliminated for the early published cases due to lack. The pons is the largest part of the brainstem, located above the medulla and below the midbrain.It is a group of nerves that function as a connection between the cerebrum and cerebellum (pons is Latin for bridge). The pons develops from the embryonic metencephalon (part of the hindbrain, developed from the rhombencephalon), alongside the cerebellum

G46.3 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2021 edition of ICD-10-CM G46.3 became effective on October 1, 2020.

Central pontine myelinolysis is characterised by focal osmotic demyelination within the pons. Its clinical presentation varies, but may include acute paralysis, dysarthria and dysphagia. The cause is traditionally associated with overzealous correction of hyponatraemia in patients who are malnourished, alcoholic or chronically ill. However, it may develop in the context of normal serum sodium. Lateral medullary stroke is typically associated with increased likelihood of occurrence of dysphagia and exhibits the most severe and persistent form. Worldwide little research exists on dysphagia in brainstem stroke. An estimated 15% of all patients admitted to stroke rehabilitation units experience a brainstem stroke out of which about 47% suffer from dysphagia Lateral medullary syndrome. The lateral medullary syndrome (Wallenberg's syndrome) is most often caused by occlusion of the intracranial segment of the vertebral artery (VA), less commonly; it is caused by occlusion of the posterior inferior cerebellar artery (PICA). The syndrome is characterized by sensory deficit

Osmotic demyelination syndrome (ODS) is an uncommon disorder, characterized by non-inflammatory demyelination involving the pons and other areas of the central nervous system, which may occur for instance as a consequence of an overly rapid correction of hyponatraemia [].Here we report a case of ODS occurred after correction of hyponatraemia with isotonic saline solution in a pregnant woman. A large portion of the central nervous system is dedicated to vision and therefore strokes have a high likelihood of involving vision in some way. Vision loss can be the most disabling residual effect after a cerebral infarction. Transient vision problems can likewise be a harbinger of stroke and prompt evaluation after recognition of visual symptoms can prevent future vascular injury. In this.
