Abstract

We present a child aged 2 years 3 months who suffered heat stroke after being accidentally locked in a car during summer. She was unconscious with hyperthermia on admission and later showed biochemical evidence of liver, cardiac and muscle injury and associated electrolyte imbalance. Her level of consciousness gradually improved, but she showed evidence of cortical blindness, which had improved on follow-up. MR imaging on the 5th day revealed bilateral hippocampal hyperintensities along with hyperintensities in the cerebellum and in the cerebral cortex. Previous case reports of imaging in heat stroke revealed involvement of the cerebellum, thalami, basal ganglia and scattered cerebral involvement. We report this unique finding of hippocampal hyperintensities due to heat stroke.
