Pons: Unilateral lesion in the dorsal pontine tegmentum in the caudal third of the pons
- Basilar artery: Paramedian branches
- Basilar artery: Short circumferential arteries
Signs & Symptoms
|Contralateral||Weakness – upper and lower extremity||Corticospinal tract|
|Ipsilateral||Weakness – face – entire side||VII nucleus / fascicle|
|Ipsilateral||Lateral gaze weakness||PPRF or CN VI nucleus|
Unilateral lesion in the dorsal pontine tegmentum in the caudal third of the pons.
- Contralateral hemiplegia (with facial sparing) due to corticospinal tract involvement
- Ispilateral peripheral-type facial palsy, due to cranial nerve VII nucleus/fascicle involvement
- Inability to move the eyes conjugately to the ipsilateral side due to paramedian pontine reticular formation and/or abducens nerve nucleus involvement. That is, patient is unable to look toward the lesion.
This is also called Millard-Gubler syndrome.
