Tour 1: Next/Previous/Start: This large cerebral infarct occurred in the setting of atrial fibrillation
and caused a dense fluent aphasia. The CT scan shown here was
obtained 5 days after the onset of stroke symptoms. View the temporal movie of this slice to see the evolution of
the lesion over the 5 day period. Significant swelling in the infarcted
area produces obvious shift of the midline by day 5. This
corresponded clinically to a diminished level of arousal, which
resolved after 2 days.
