Contrast-Induced Encephalopathy Following Cerebral Angiography: A Case Report and Literature Review

Contrast-induced encephalopathy (CIE) is a rare neurotoxic complication that occurs following administration of contrast agents. Diagnosis is often challenging due to the wide variety of clinical presentation, which can include transient neurological deficits such as vision changes, sensory deficits, paralysis, and altered mental status. It is self-limited, and symptoms usually resolve within 48-72 hours. It is important to consider contrast-induced encephalopathy in a patient that experiences neurological defects following procedures using contrast agents. This report describes a 58-year-old male who subsequently developed contrast-induced encephalopathy following a diagnostic cerebral angiogram.
