Abstract

A 104-year-old woman suddenly developed right hemiplegia and aphasia due to cardioembolic stroke. At onset, she fell down and bruised her face. Although computed tomography (CT) did not demonstrate apparent intracranial hemorrhage, diffusion-weighted and FLAIR magnetic resonance imaging (MRI) revealed a small amount of subdural hematoma. Accordingly, we did not use intravenous recombinant tissue-type plasminogen activator for her stroke. MRI appears to be more capable of detecting intracranial hemorrhage than does CT. For patients with hyperacute ischemic stroke who have a recent history of head injury, MRI may be advantageous over CT as a decisive diagnostic tool for indicating thrombolytic therapy.
