Intrathecal instillation of metrizamide has provided a useful tool for the in vivo evaluation of smaller structures adjacent to or within the subarachnoid cisterns. The authors report a case in which metrizamide filled the thin subarachnoid space surrounding the optic nerve in its course through the orbit. The finding appears to be infrequent, however, since it was not observed in any instance in a review of 80 metrizamide computed tomographic cisternograms in patients with normal intracranial pressure.
鞘内注入甲泛葡胺为蛛网膜下池附近或其中较小结构的体内评估提供了一种有用的工具。作者报告了一例甲泛葡胺填充视神经在眼眶行程中周围蛛网膜下腔薄层的病例。然而，这一发现似乎并不常见，因为在对80例颅内压正常患者的甲泛葡胺计算机断层脑池造影复查中未在任何实例中观察到。
