Lateral pontine syndrome
|Lateral pontine syndrome|
Damage to the following areas produces symptoms (from medial to lateral):
|Lateral spinothalamic tract||Contralateral loss of pain and temperature from the trunk and extremities.|
|Facial nucleus & facial Nerve (CN.VII)||(1) Ipsilateral paralysis of the upper and lower face (lower motor neuron lesion). (2) Ipsilateral loss of lacrimation and reduced salivation. (3) Ipsilateral loss of taste from the anterior two-thirds of the tongue. (4) Loss of corneal reflex (efferent limb).|
|Spinal trigeminal nucleus and tract||Ipsilateral loss of pain and temperature sensation from the face (facial hemianesthesia)|
|Vestibular Nuclei and intraaxial nerve fibers||Nystagmus, nausea, vomiting, and vertigo|
|Cochlear nuclei and intraaxial nerve fibers||Hearing loss - ipsilateral central deafness|
|Middle & inferior cerebellar peduncle||Ipsilateral limb and gait ataxia|
|Descending sympathetic tract||Ipsilateral Horner's syndrome (ptosis, miosis, & anhydrosis)|
It can be caused by an interruption to the blood supply of the anterior inferior cerebellar artery or circumferential arteries.
