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 ...
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 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]
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 laterodorsal tegmental nucleus (or lateroposterior tegmental nucleus) is a nucleus situated in the brainstem, spanning the midbrain tegmentum and the pontine tegmentum. [1] Its location is one-third of the way from the pedunculopontine nucleus to the thalamus, inferior to the pineal gland.
Human brainstem blood supply description. Posterior cerebral artery is #6, and midbrain is behind it.. Claude's syndrome is caused by midbrain infarction as a result of occlusion of a branch of the posterior cerebral artery. [2]

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 ...
