Abstract
A 27-year-old man developed a persistent bitemporal hemianopia after severe head trauma sustained in a high-speed motor vehicle accident. The initial brain MRI revealed hemorrhagic contusion of the optic chiasm. A brain MRI performed 4 weeks later demonstrated complete chiasmal transection, a phenomenon rarely documented with imaging.
摘要
一位 27 岁男性在一场高速机动车事故中遭受严重头部创伤后出现持续性双眼颞侧偏盲。最初的脑部 MRI 显示视交叉出血性挫伤。4 周后进行的脑部 MRI 显示完全性视交叉横断，这是一种很少通过影像学记录到的现象。
