Contrast-induced encephalopathy (CIE) is a rare complication of the intravascular application of a contrast agent. CIE can be manifested by headache, cortical blindness, consciousness disorders, seizures, or focal neurological defi cit. Neurological symptoms are typically transient with temporary abnormal fi ndings on a brain scan. Urgent neuroimaging is important to obtain the correct diagnosis, especially in cases that require an acute management and treatment. We present a case of CIE after a digital subtraction angiography of the vertebral arteries in the patient with a symptomatic pre-occlusive stenosis of the posterior cerebral artery (Ref. 36).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
