In a case report Govindasamy et al. from the James Cook University Hospital, Middlesbrough published in Cureus to describe a rare complication—transient cortical blindness—following endovascular treatment of a basilar tip aneurysm. A 60-year-old woman developed transient cortical blindness post-endovascular embolization for a 1.2 cm incidental basilar tip aneurysm. Symptoms included bilateral vision loss and confusion, with full visual recovery within 48 hours. MRI showed no infarction, and Posterior Reversible Encephalopathy Syndrome (PRES) was ruled out due to the absence of other characteristic features. The authors suggest contrast-induced transient cortical blindness as the most likely etiology 1)
Critical Review
This is a single-case report documenting a rare but recognized complication of endovascular procedures involving posterior circulation—the transient cortical blindness, likely due to contrast-induced neurotoxicity. The case is clearly described and provides a succinct narrative of presentation, procedural details, and post-operative events. However, the scientific value remains modest due to several limitations:
