Transient cortical blindness is an uncommon but well-known complication following cerebral angiography. One possible cause of this complication is an adverse reaction to contrast agent, resulting in an osmotic disruption of the blood-brain barrier that seems to be selective for the occipital cortex. We report the case of a 16-year-old male patient with cortical blindness after intravenous application of nonionic contrast agent during CT angiography performed because of seizure that was attributed to thrombosis of the basilar artery on the basis of clinical findings. To our knowledge, the development of cortical blindness after CT angiography has not been described in the literature. The patient's symptoms were triggered by hyponatriemia and diabetes insipidus.
短暂性皮质盲是脑血管造影术后一种罕见但广为人知的并发症。这种并发症的一个可能原因是对造影剂的不良反应，导致血脑屏障的渗透性破坏，这种破坏似乎对枕叶皮质具有选择性。我们报告一例16岁男性患者，因癫痫发作行CT血管造影时静脉注射非离子型造影剂后出现皮质盲。根据临床表现，癫痫发作归因于基底动脉血栓形成。据我们所知，CT血管造影术后发生皮质盲在文献中尚未见报道。该患者的症状由低钠血症和尿崩症引发。
