[A case of heat stroke with cortical laminar necrosis on vascular boundary zones].

We report a 10-month-old boy with heat stroke because he was left in a car. He showed hyperthermia, coma and convulsions at the time of his admission. Liver dysfunction and coagulopathy were observed, but they were improved after several days. Consciousness was gradually recovered, but currently he shows neurological sequelae. Cranial CT showed brain edema until the 7th hospital day. Cranial MRI on the fortieth hospital day showed the finding of cortical laminar necrosis in the vascular boundary zones. This finding suggest that brain ischemia was related with the neurological involvement of heat stroke.
