Key result
Diagnostic cerebral angiography with contrast exposure is linked to rare transient cortical blindness.
Why the study?
Transient cortical blindness is a rare complication of cerebral angiography, and highlighting this case emphasizes the importance of recognizing this diagnosis of exclusion.
Case Report (n=1)
Transient cortical blindness is a rare but important complication of contrast exposure during cerebral angiography that must be recognized as a diagnosis of exclusion.
Transient cortical blindness (TCB) is a rare complication of cerebral angiography with an incidence between 0.24% and 1%. TCB occurs due to hypothesized visual cortex neurotoxicity from contrast exposure, particularly with posterior circulation injections and higher contrast doses. We present a case of TCB following diagnostic cerebral angiography that highlights the importance of recognizing this diagnosis of exclusion.

Fedorova et al. (2026) conducted a case report in Transient cortical blindness (n=1). Diagnostic cerebral angiography (contrast exposure) was evaluated on Transient cortical blindness. Diagnostic cerebral angiography with contrast exposure can lead to transient cortical blindness, a rare complication requiring recognition as a diagnosis of exclusion.
