Abstract: Lateral medullary syndrome is a common presentation of posterior circulation ischemia that presents with ipsilateral Horner syndrome, ipsilateral facial numbness, contralateral body numbness, vestibular symptoms, ataxia, dysphagia, and dysarthria. Here, we describe an 84-year-old who presented to the hospital with right upper motor neuron facial weakness and gait abnormality found to have a right lateral medullary ischemic stroke. Multiple MRI's, including with thin brainstem slices, were without evidence of pontine, midbrain or cerebral ischemia outside the medulla. We postulate that the patient's ipsilateral upper motor neuron facial weakness was caused by involvement of aberrant corticobulbar fibers in the medulla ascending to the facial nucleus.
