Heat stroke is a serious medical condition that can cause multiple organ dysfunction, including central nervous system damage. The complications of heat stroke occur because of hypoperfusion, an inflammatory response, and thrombosis, resulting in variable imaging findings. This report describes a rare case of rapidly progressive heat stroke with rhabdomyolysis and acute kidney injury in a 53-year-old woman with atypical brain computed tomography and magnetic resonance imaging findings involving the bilateral cerebral cortex and deep gray matter but excluding the cerebellum. She had an increased diffusion-weighted imaging signal and a reduced apparent diffusion coefficient within the bilateral basal ganglia and cerebral cortex, which have not been reported previously. These findings indicate that cytotoxic edema is a potential mechanism of brain damage in individuals with heat stroke.
中暑是一种严重的医学状况，可导致多器官功能障碍，包括中枢神经系统损伤。中暑的并发症是由于灌注不足、炎症反应和血栓形成引起的，导致影像学表现多样。本报告描述了一例罕见的快速进展性中暑病例，该病例发生在一名53岁女性身上，伴有横纹肌溶解和急性肾损伤，其脑部计算机断层扫描和磁共振成像结果不典型，累及双侧大脑皮质和深部灰质，但不包括小脑。她双侧基底神经节和大脑皮质内的扩散加权成像信号增加，表观扩散系数降低，这在以前尚未见报道。这些发现表明，细胞毒性水肿是中暑患者脑损伤的一种潜在机制。
