Medial pontine syndrome
From Wikipedia, the free encyclopedia
|Medial pontine syndrome|
|Pons. (Medial pontine syndrome affects structures at the bottom of the diagram: the corticospinal tract, abducens nerve, and occasionally the facial nerve. Medial lemniscus is also affected, but not pictured.)|
|Classification and external resources|
|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.
