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 ...
The pontine nuclei are located within the basilar pons. Also nearby are the raphe nuclei and the locus coeruleus, nuclei of cranial nerves 9-12, and the dorsal respiratory group, which are located further caudally in the brainstem. The dorsal respiratory group are connected to the pneumotaxic and apneustic centres of the pontine tegmentum.
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 .
Symptoms of a brainstem stroke frequently include sudden vertigo and ataxia, with or without weakness. Brainstem stroke can also cause diplopia, slurred speech and decreased level of consciousness. A more serious outcome is locked-in syndrome. [citation needed]
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 fasciculus. There is involvement of the fifth to eighth cranial nerves, central sympathetic fibres ...
The symptoms of a mini and major stroke aren't much different, but Dr. Itrat says ones from a TIA will resolve in a short timeframe. In either case, calling for help is critical.
Millard–Gubler syndrome is named after two French physicians, Auguste Louis Jules Millard (1830–1915), who first identified the disorder in 1855, and Adolphe-Marie Gubler (1821–1879), who described the disease in a medical paper one year later.
The superior pontine sulcus separates the pons from the midbrain. [7] Posteriorly, the pons curves on either side into a middle cerebellar peduncle. [4] A cross-section of the pons divides it into a ventral and a dorsal area. The ventral pons is known as the basilar part, and the dorsal pons is known as the pontine tegmentum. [3]
