Anterior Spinal Artery Syndrome
At level of SC
- Ipsilateral loss of voluntary motor control below the lesion (CST)
- Disruption of spinal reflexes at the level of the lesion (reflexes are intact
below the lesion)
Anterior Spinal Artery Syndrome
Level of the caudal-medulla
- Loss of voluntary motor control below the lesion (CST), bilateral or
- corticobulbar axons not affected
Brown-Sequard Syndrome
- Ipsilateral loss of voluntary movement below lesion (CST; RST, if cervical)
- And, of course, loss of ipsilateral fine touch, proprioception and contralateral loss of pain and temperature
Medial Pontine Syndrome
- Contralateral impairment of voluntary movement of body below the lesion (CST)
- Contralateral impairment of fine touch (medial lemniscus)
- Damage to abducens nerve or nucleus or to the PPRF can impair lateral eye movements toward the side of the lesion
Lateral Pontine Syndrome
- Ataxia, unsteady gait, fall toward side of lesion (middle and superior cerebellar
peduncles—caudal and rostral pons, respectively)
- Vertigo, nausea, nystagmus, deafness, tinnitus, vomiting (vestibular and cochlear nerves and nuclei—CN 8)
- Ipsilateral paralysis of facial muscles (facial motor nucleus, if caudal pons)
- Ipsilateral paralysis of jaw muscles (trigeminal motor nucleus, midpontint lesions)
- Ipsilateral Horner’s Syndrome (descending hypothalamospinal fibers)
- Loss of pain and temperature in the ipsilateral face (spinal trigeminal tract and
nucleus) and contralateral body (spinothalamic tract)
Middle Cerebral Artery Occlusion
- If only the cortex affected, loss of voluntary control
of the contralateral body
- If the internal capsule is affected (more likely), the patient could suffer
a. Contra loss of voluntary movement of body (CST)
b. Contralateral loss of voluntary movement of lower face (CBT)
