Lateral pontine syndrome, also known as Marie-Foix syndrome or Marie-Foix-Alajouanine syndrome [1] is one of the brainstem stroke syndromes of the lateral aspect of the pons. A lateral pontine syndrome is a lesion which is similar to the lateral medullary syndrome , but because it occurs in the pons , it also involves the cranial nerve nuclei ...
Several different types of magnetic resonance imaging (MRI) may be employed in diagnosis: MRI without contrast, Gd contrast enhanced T1-weighted MRI (GdT1W) or T2-weighted enhanced MRI (T2W or T2*W). Non-contrast enhanced MRI is considerably less expensive than any of the contrast enhanced MRI scans. The gold standard in diagnosis is GdT1W MRI.
Central pontine myelinolysis; Other names: Osmotic demyelination syndrome, central pontine demyelination: Axial fat-saturated T2-weighted image showing hyperintensity in the pons with sparing of the peripheral fibers, the patient was an alcoholic admitted with a serum Na of 101 treated with hypertonic saline, he was left with quadriparesis, dysarthria, and altered mental status
Medial inferior pontine syndrome is a condition associated with a contralateral hemiplegia. [ citation needed ] "Medial inferior pontine syndrome" has been described as equivalent to Foville's syndrome .
upper dorsal pontine syndrome, Basillar artery runs down the middle(in above image) and blockage is cause of this condition. Diagram of the arterial circulation at the base of the brain (inferior view). Diagnostic method: Cect/ncct brain, mri brain
It is most frequently caused by lesions such as vascular disease and tumors involving the dorsal pons. Structures affected by the lesion are the dorsal pons (pontine tegmentum) which comprises paramedian pontine reticular formation (PPRF), nuclei of cranial nerves VI and VII , corticospinal tract , medial lemniscus , and the medial longitudinal ...
Occlusion of AICA is considered rare, but generally results in a lateral pontine syndrome, also known as AICA syndrome.The symptoms include sudden onset of vertigo, vomiting, nystagmus, dysarthria, falling to the side of the lesion (due to damage to vestibular nuclei), and a variety of same-side features including hemiataxia, loss of all types of sensation of the face (due to damage to the ...
The paramedian pontine reticular formation (PPRF) is a subset of neurons of the oral and caudal pontine reticular nuclei. With the abducens nucleus it makes up the horizontal gaze centre . [ 1 ] It is situated in the pons adjacent to the abducens nucleus . [ 2 ]
