lateral pontine syndrome

Lateral pontine syndrome, also known as Marie-Foix syndrome or Marie-Foix-Alajouanine syndrome, refers to one of the brainstem stroke syndromes of the lateral aspect of the pons.

Clinical presentation

There is a characteristic clinical picture from the involvement of the following pontine structures :

• corticospinal tract: contralateral hemiplegia/hemiparesis
• spinothalamic tracts: contralateral loss of pain and temperature sensation
• cerebellar tracts: ipsilateral limb ataxia
• facial nerve (CN VII) nucleus: ipsilateral facial paralysis
• vestibulocochlear nerve (CN VIII) nuclei: ipsilateral hearing loss, vertigo and nystagmus

Pathology

The lateral pontine syndrome occurs due to occlusion of perforating branches of the basilar and anterior inferior cerebellar (AICA) arteries .

History and etymology

The syndrome was first described by Pierre Marie (1853-1940), Charles Foix (1882-1927), and Théophile Alajouanine (1890-1980), French neurologists, in 1922 .
