Figure 3 Representative Images of brain CT scanBrain computed tomography (CT) scan of a 22-year-old male heatstroke patient admitted with persistent coma showed diffuse encephalic swelling, compressed or occluded ventricles, sulci, and cisterna, and extensive subarachnoid hemorrhage on the 3rd day after admission (A). Another 27-year-old male heatstroke patient admitted with GCS of 5 survived; although his brain CT scan did not show swelling or edema at admission (B1), and a light encephalic swelling was shown by a CT scan 6 days later (B2), his GCS improved after admission and he survived.
