History and etymology The syndrome was first described by Pierre Marie (1853-1940), Charles Foix (1882-1927), and Thophile Alajouanine (1890-1980), French neurologists, in 1922 3. Lateral pontine syndrome (Marie-Foix syndrome) . For horizontal gaze, it is the paramedian pontine reticular formation (PPRF) in the mid-pons region that represents the horizontal gaze center generating conjugate horizontal movements for each eye.21 For example, a horizontal right conjugate gaze palsy would involve the left FEF sending a signal via the superior colliculus to the right PPRF.

The Superior Foville Syndrome is a rare clinical feature of stroke or brain hemorrhage.

Pontine hemorrhage caused by high blood pressure is usually located more medially and damages both CN VI nucleus and CN . Middle cerebral peduncle is supplied by branches of the superior cerebellar and anterior inferior cerebellar arteries. The superior salivatory (salivary) nucleus is located in the lower pontine tegmentum, dorsal and lateral to the motor facial nerve nucleus. The complex and crowded anatomy of the superior orbital fissure produces a characteristic pattern of cranial nerve, pupillary and extraocular findings. This fissure lies at the back of the orbit between the lesser and great wing of the sphenoid. Results The clinical presentations included pure motor hemiparesis (PMH) in 17, sensorimotor stroke in 3, ataxic hemiparesis (AH) in 4, and dysarthria . She was evaluated by neuro-ophthalmology who confirmed the diagnosis of 8 and syndrome. vertical diplopia that worsens with downgaze. The MRI findings suggested osmotic myelinolysis (pontine and extrapontine), which developed as a complication of rapid correction of hyponatraemia associated with renal disease.
