| Medial pontine syndrome |
Medial inferior pontine syndrome is a condition associated with a contralateral hemiplegia."Medial inferior pontine syndrome" has been described as equivalent to Foville's syndrome.[1]
Although medial pontine syndrome has many similarities to medial medullary syndrome, because it is located higher up the brainstem in the pons, it affects a different set of cranial nuclei.
| Structure affected | Presentation | |
|---|---|---|
| Corticospinal tract | Contralateral spastic hemiparesis | |
| Medial lemniscus | Contralateral PCML (aka DCML) pathway loss (tactile, vibration, and stereognosis) | |
| Abducens nerve | Strabismus (ipsilateral lateral rectus muscle paralysis - the affected eye looks down and towards the nose). Abducens nerve lesion localizes the lesion to inferior pons. |
Depending upon the size of the infarct, it can also involve the facial nerve.
Medial pontine syndrome results from occlusion of paramedian branches of the basilar artery.
