In a case of traumatic avulsion of the optic nerve at the anterior chiasm, MR imaging provided highly specific images of the injury site, including the absence of the optic nerve within the optic canal and the point of transection at the anterior portion of the chiasm. This was confirmed clinically and histopathologically. MR imaging should be considered in cases of suspected chiasmal injury.
在一例视交叉前部视神经创伤性撕脱病例中,磁共振成像(MR成像)提供了损伤部位的高度特异性图像,包括视神经管内视神经缺失以及视交叉前部的横断点。这在临床和组织病理学上得到了证实。对于疑似视交叉损伤的病例,应考虑进行MR成像检查。
