关于人脑严重低血糖性损伤后的系列改变,以前很少有文献报道。本文作者用反复CT扫描和MRI研究了4例糖尿病患者重度低血糖后植物状态的脑部系列改变,并同作者用同一方法研究过的心脏停跳后人脑的改变进行了比较。 结果从发病到第14天时,所有低血糖患者连续CT扫描显示在尾状核和豆状核有持续性的低密度损害和短暂性的强化,而在大脑皮层仅有短暂性的强化。在发病后8天到12个月,连续MR成像显示在尾状核、豆状核、大脑皮层、黑质和/或海马的T_1和T_2加权像上分别有均匀一致的持久的对称性损害。本研究及文献复习结果表明:第一,神经放射学证实低血糖昏迷后人脑可以出现特殊的对称性的低血糖损害。第二,这种低血糖 There have been few reports of a series of changes in the human brain following severe hypoglycemic injury. The authors used repeated CT scans and MRIs to study the brain-like changes in the state of the plant after severe hypoglycaemia in four diabetic patients and compared them with the changes in human brain after the same method of cardiac arrest. Results From the onset to day 14, continuous CT scans of all hypoglycemic patients showed persistent low-density lesions and transient enhancement in the caudate and putamen, while only transient enhancement in the cerebral cortex. From 8 days to 12 months after onset, continuous MR imaging showed consistent long-lasting symmetry damage on the T 1 and T 2 weighted images of the caudate, putamen, cerebral substantia nigra and / or hippocampus, respectively. The results of this study and review of the literature show that: First, neuroradiology confirms that hypoglycemic damage can occur in the human brain with a special symmetry after hypoglycemic coma. Second, this hypoglycemia
