The two pathologies in the title could also be differentiated in other ways, for example, the speed of onset, additional symptoms and signs, etc. Atypical features in our case, which questioned the diagnosis of a simple lateral medullary syndrome were as follows: Contralateral hemiparesis. A unilateral LMN lesion has more severe effects than does a unilateral UMN lesion. The facial nerve (the labyrinthine segment) is the seventh cranial nerve, or simply CN VII.It emerges from the pons of the brainstem, controls the muscles of facial expression, and functions in the conveyance of taste sensations from the anterior two-thirds of the tongue. Video on FACIAL NERVE PALSY created by world-class clinical faculty. Which exact speech disorder accompanies a LMN lesion depends on the nerve or nerves involved. This is the classic “lower motor neuron” lesion of facial paralysis, and produces a facial nerve palsy. Common symptoms include, but are not limited to: Muscle weakness or paralysis. Usually 80% recover within 3 months. Further workup of facial nerve palsy is dictated by clinical suspicion of the underlying cause of facial weakness. This resembles, superficially, a bulbar palsy, hence pseudobulbar. History & Signs: drooling; facial paralysis; vertical nystagmus.
