Transient global amnesia after cerebral angiography still occurs: Case report and literature review.

Transient global amnesia is considered a very rare complication of diagnostic cerebral angiography, and has been reported only in a limited number of case reports more than 15 years ago. We describe a patient experiencing transient global amnesia following cerebral digital subtraction angiography. While the condition by definition is self-limiting, its differential diagnoses may cause severe morbidity and/or mortality if left untreated. It is therefore important to build and maintain awareness of transient global amnesia as a possible complication of cerebral angiography.
