Medial medullary Syndrome results from an occlusion of a vertebral artery or the anterior spinal artery.
Pts. may have 2 long tract signs caused by a lesion of the MEDIAL LEMNISCUS & th CORTICOSPINAL TRACT, combined w/ a lesion of the HYPOGLOSSAL NERVE.
- contralateral spastic hemiparesis & CL loss of touch vibration & pressure in the limbs &
trunk. Lesion of the hypoglossal nerve result in DYSARTHRIA & deviation of the tongue
toward the side of the lesion on protrusion.
These pts. have an inferior alternating hemiplegia - spastic weakness in the limbs on the side CL to the lesion & tongue weakness ipsilateral to the lesion.

Lateral medullary syndrome is caused by the lesion of the posteriior inferior cerebellar artery.
it affects the inferior cerebellar peduncle causing ipsilateral cerebellar signs, dysmetria, ataxia, loss of unconscious proprioception, past pointing etc.
it also causes contralateral loss of pain and temperature sensation, crude touch etc. trunk, upper and lower limb( spinothalamic tract)
there is ipsilateral loss of pain and temperature, on the face.( spinal tract of trigeminal)
Ipsilateral nucleus ambiguous lesions, causes difficulty in swallowing, absent gag reflex, ipsilateral palatal paralysis, the soft palate is pulled towards the normal side, hoarseness of voice etc.
Horners syndrome on the ipsilateral side.
Correct if wrong anywhere please or add?
