Abstract

Lateral medullary syndrome (LMS), known as Wallenberg's syndrome and posterior inferior cerebellar artery syndrome, is a rare cause of stroke. It often results from thrombosis or emboli of the vertebral artery or posterior inferior cerebellar artery. The triad of Horner's syndrome, ipsilateral ataxia, and ipsilateral hyperalgesia clinically identify patients with LMS. We report a case of a 62-year-old diabetic, hypertensive male who presented with symptoms involving the left lateral dorsal medulla along with partial Horner's syndrome, left lateral rectus palsy, and left lower motor neuron-type facial palsy. Atypical presentation in LMS could be explained by infraction of left facial colliculus in addition to the left lateral medulla. Association of these entities with Wallenberg's syndrome is atypical features in our case, which questioned the diagnosis of a simple LMS.
