Which nerve is involved in Weber Syndrome?
Weber syndrome, classically described as a midbrain stroke syndrome and superior alternating hemiplegia, involves oculomotor fascicles in the interpeduncular cisterns and cerebral peduncle, thereby causing ipsilateral third nerve palsy with contralateral hemiparesis.
What is Millard Gubler syndrome?
Millard-Gubler syndrome (MGS), also known as facial abducens hemiplegia syndrome or ventral pontine syndrome, is one of the classical crossed brainstem syndromes characterized by a unilateral lesion of the basal portion of the caudal pons involving fascicles of abducens (VI) and the facial (VII) cranial nerves and the …
How is Sturge-Weber syndrome diagnosed?
A diagnosis may be straightforward in an infant with a port-wine birthmark, glaucoma, evidence of cerebral involvement and neuroimaging findings consistent with a diagnosis of SWS. Diagnosis can be more difficult in infants who have a port-wine birthmark, but no neurological symptoms.
When do Sturge-Weber symptoms start?
Consequently, the specific symptoms and severity of the disorder can vary dramatically from one person to another. Symptoms are usually present at birth (congenital), yet the disorder is not inherited and does not run in families. Some symptoms may not develop until adulthood.
Why does Claude syndrome cause contralateral ataxia?
Claude’s syndrome is a distinctive brainstem syndrome characterized by ipsilateral third cranial nerve palsy with contralateral hemiataxia and is due to an intrinsic or extrinsic lesion in the midbrain. We report a case of Claude’s syndrome caused by neurocysticercosis infection.
What is pontine syndrome?
A pontine cerebrovascular accident (also known as a pontine CVA or pontine stroke) is a type of ischemic stroke that affects the pons region of the brain stem. A pontine stroke can be particularly devastating and may lead to paralysis and the rare condition known as Locked-in Syndrome (LiS).
What is uncrossed hemiplegia?
Lesions above the level of the brainstem result in uncrossed hemiplegia. For example, a lesion in the left internal capsule would result in right hemiplegia and right facial weakness of the upper motor neuron type.
What does Dysmetria mean?
Dysmetria is a condition in which there is improper measuring of distance in muscular acts; hypermetria is overreaching (overstepping) and hypometria is underreaching (understepping).
What is lateral medullary syndrome?
Lateral medullary syndrome, also known as Wallenberg syndrome, is a clinical syndrome caused by an acute ischemic infarct of the lateral medulla oblongata. This is most commonly due to occlusion of the intracranial portion of the vertebral artery followed by PICA and its branches 1-3.
What are the symptoms of pons?
Symptoms of a Pons Stroke
- Balance issues.
- Difficulty swallowing.
- Dizziness.
- Double vision.
- Loss of sensation and coordination.
- Nausea.
- Numbness.
- Slurred speech.
What is contralateral hemiparesis?
Paralysis occurring on the side of the body opposite to the side of the brain in which the causal lesion occurs.
