It is lateral medullary syndrome.

Contralateral loss of
pain and thermal sense on body = spinal lemniscus

Ipsilateral loss of pain and thermal sense on face =tract and nucleus of spinal trigeminal

Dysphagia, hoarseness
diminished gag nerves reflex = n. ambiguus,

Ipsilateral Horner syndrome (miosis,ptosis, anhidrosis, flushing of face) = desc. hypoth. fibers

Ataxia to the ipsilateral side = restiforme

i donīt know any mnemonics for all this crap, just going to have to painfuly memorize it
rolling eyes
