We present a case of heat stroke with rare magnetic resonance (MR) imaging manifestations. In addition to abnormal high signals in bilateral cerebellum and basal ganglia seen on T2-weighted MR images (T2WI), the case showed diffuse cerebral cortical high signals on T2WI and diffusion-weighted images (DWI). Heat stroke with diffuse hypoperfusion to the brain due to diversion of blood circulation was hypothesized as the cause of brain injury, including the cerebral cortex.
