New-Onset Fixation-Off Sensitivity or Scotosensitivity in an Adult Male After Bilateral Embolic Strokes of the Parietal and Occipital Regions.

A 50-year old male suffered new-onset clinical and subclinical seizures provoked by acute bilateral embolic strokes in the parietal and occipital regions as a complication of aortic valve replacement surgery. After successful treatment of these refractory symptomatic seizures with intravenous propofol and antiseizure medications, video-EEG recordings revealed acute and transient fixation-off sensitivity or scotosensitivity that resolved within 10 weeks.
