Abstract 174: A Rare Case of Short‐Sequence Wallenburg and Dejerine Syndromes Secondary to Symptomatic Intracranial Atherosclerotic Disease

Dejerine Syndrome, a rare clinical syndrome representing 0.5% of ischemic strokes, is caused by occlusion of the anterior spinal artery or its branches, leading to infarction of the medial medulla. Affected patients classically present with ipsilateral tongue weakness with contralateral hemianesthesia and hemiparesis. Wallenburg Syndrome is a more common syndrome caused by disease of the posterior inferior cerebellar artery (PICA) or the vertebral artery, classically causing crossed sensory loss, vertigo, and an ipsilateral Horner's syndrome. Here, we present a patient with symptomatic intracranial atherosclerotic disease (ICAD) presenting with both Wallenburg and Dejerine Syndromes on separate occasions over a six‐month period.
