  • Abstract
  • Look Inside

We reported a patient with transient ischemic attack (TIA) , subsequently evolving to a cerebral infarction, in whom ictal diffusion-weighted magnetic resonance imaging ( MRI ) detected early ischemic lesion in the left hemisphere.

The patient was a 30-year-old right-handed male medical doctor, who had an in-hospital episode of TIA with obtundation and right hemiparesis, which lasted for 150 minutes. Ictal diffusion-weighted MRI ob-tained 110 minutes after symptom onset demonstrated an area of high signal intensity in the left striatum and corona radiata, whereas T 2-weighted and FLAIR im-ages were entirely normal.
