This is lateral medullary/PICA/Wallenberg syndrome. The woman has damage in the sympathetic chain (sensory syndromes are lateral according to the rule of 4s) resulting in Horner syndrome, spinothalamic tract (pain/temp which are also sensory), and CN IX and CN X dysfunction resulting in the dysphagia/dysarthria (helps us localize to the medulla).
nala_ulaAlso, just to add, FA specifies that Nucleus ambiguus effects (dysphagia, hoarseness, decreased gag reflex) are specific to PICA lesions. +12019-06-16T20:52:52Z
