我们描述了磁共振的变化，发生3周和6周后，自杀企图与氰化物。氰化物的毒性会导致损伤，主要是基底神经节，这些变化在第一次MR图像上表现为信号强度的改变。6周后可见大面积出血性坏死。我们的病例显示，氰化物中毒3周后，大脑皮质中央出现沿着的假板坏死，这表明感觉运动皮质也是中毒性坏死的部位，因为它具有高度的氧依赖性。
We describe MR changes that occurred 3 and 6 weeks after a suicide attempt with cyanide. The toxicity of cyanide causes damage, primarily to the basal ganglia, and those changes were visible as altered signal intensity on the first MR images. Extensive areas of hemorrhagic necrosis were seen 6 weeks later. Our case shows pseudolaminar necrosis along the central cerebral cortex 3 weeks after cyanide poisoning, showing that the sensorimotor cortex is also a site for toxic necrosis because of its high oxygen dependency.
