Contrast-Induced Encephalopathy Mimicking Stroke after Cardiac Catheterization: A Case Report

An 84-year-old woman with hypertension and chronic kidney disease had a non-ST segment elevation myocardial infarction. After undergoing successful cardiac catheterization and stent placement, she developed left-sided weakness from contrast-induced encephalopathy, which is often confused with stroke. Management involved avoiding further contrast exposure, opting for MRA and MRV, and treatment with IV hydration and steroids. This case emphasizes the importance of careful imaging choices in managing contrast-induced encephalopathy to prevent additional neurologic damage.
