An Acute Ischemic Stroke Resulting from Aortic Dissection.

A 39-year-old man with syncope and persistent dizziness was sent to stroke emergency. Patient's diffusion magnetic resonance imaging of brain showed acute ischemia in right cerebella and right occipital lobe, thus intravenous recombinant tissue plasminogen activator was given to him. However, the patient behaved rather restless with repeated complaint of back and thoracic pain. Further thorax computed tomography angiography confirmed that the underlying cause turned out to be aortic dissection.
