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.
我们报告一名2岁3个月大的儿童，其在夏季意外被锁在车内后发生中暑。入院时她昏迷且体温过高，随后出现肝脏、心脏和肌肉损伤以及相关电解质失衡的生化证据。她的意识水平逐渐改善，但出现了皮质盲的迹象，随访时有所改善。第5天的磁共振成像显示双侧海马高强度信号，同时小脑和大脑皮质也有高强度信号。先前关于中暑影像学的病例报告显示小脑、丘脑、基底神经节受累以及大脑散在受累。我们报告了因中暑导致海马高强度信号这一独特发现。
