An Unusual Case Report of Pseudothalamic Pattern of Sensory Loss in Lateral Medullary Syndrome.

Lateral medullary syndrome is a collection of different neurological symptoms after ischemic/hemorrhagic insult to either the posterior inferior cerebellar artery/vertebral artery or rarely the anterior inferior cerebellar artery, causing infarction of ipsilateral cerebellum and posterolateral medulla (Tiedt and Weidauer, 2013). Dizziness, nausea, vertigo, vomiting, nystagmus, ataxia, dysphagia, hoarseness of voice, ptosis, and sensory impairment of face and body are typical. Here we report an unusual presentation of a 47-year-old female who was hypertensive and diabetic and who complained of vertigo, nausea, vomiting, slurring of speech, facial deviation toward the left, and loss of pain and temperature over the right side of the face and body without any difficulty in swallowing or nasal regurgitation. The patient was eventually diagnosed with left lateral medullary syndrome, drawing attention to the rare and unusual presentation of the same.
