A 63-year-old man with several vascular risk factors presented with sudden left hemiplegia rapidly evolving to quadriparesis, dysarthria, bilateral hypoglossal palsy (video 1 on the Neurology® Web site at Neurology.org), and respiratory failure. IV thrombolysis with recombinant tissue plasminogen activator was administered. MRI confirmed bilateral medial medullary infarction (figure, A), and CT and magnetic resonance angiography showed right vertebral artery V4 occlusion, presumably atherosclerotic (figure, B). Tongue mobility recovered completely after 3 months (video 2).
(A) Diffusion-weighted-axial image: bilateral medial medullary infarct. (B) Magnetic resonance angiography: right V4 occlusion (white arrow).
Dejerine syndrome is a rare stroke syndrome; its bilateral form at the rostral level produces the characteristic “heart sign” on MRI1,2 (figure, A).
