Lateral pontine syndrome, also known asMarie-Foix syndrome, refers to one of the brainstem stroke syndromes which occurs due to occlusion of perforating branches of the basilar and anterior inferior cerebellar (AICA) arteries. This results in infarction of the lateral aspect of the pons which produces characteristic clinical picture from involvement of the following pontine structures:
- corticospinal tract leads to contralateral hemiplegia/hemiparesis.
- spinothalamic tract causes contralateral loss of pain and temperature sensation.
- cerebellar tracts causes ipsilteral limb ataxia.
- CN VII nucleus leads to ipsilateral facial paralysis.
- CN VIII vestibular and cochlear nuclei leads to ipsilateral hearing loss, vertigo and nystagmus.
