Traumatic brain damage can result in severe visual impairments including hemianopia. Lesions correlated with hemianopia can be located in any part of the retrochiasmatic optic pathway. However, traumatic lesions of the optic tract are relatively rare. We present a case with posttraumatic left homonymous hemianopia who had signal intensity change at the ipsilateral optic tract on MR imaging and ipsilateral occipital hypoperfusion on SPECT imaging.
创伤性脑损伤可导致包括偏盲在内的严重视力障碍。与偏盲相关的病变可位于视交叉后视觉通路的任何部位。然而,视束的创伤性病变相对少见。我们报告一例创伤后左侧同向性偏盲患者,其磁共振成像显示同侧视束信号强度改变,单光子发射计算机断层扫描成像显示同侧枕叶灌注不足。
