Contrast-Induced Encephalopathy After Simultaneous Embolization of Multiple Intracranial Aneurysms: A Case Report and Management

Year: 2026

Type: article

Abstract: Contrast-induced encephalopathy (CIE) is a rare but potentially serious complication associated with the administration of contrast media. We report the case of a 70-year-old woman undergoing diagnostic cerebral angiography for asymptomatic common carotid artery stenosis who developed transient drowsiness during the procedure. Shortly after angiography, she experienced generalized tonic-clonic seizures involving the left upper and lower extremities, accompanied by leftward gaze deviation. Computed tomography revealed cortical high-density signals consistent with contrast leakage, leading to a diagnosis of CIE. This case highlights the need for vigilant monitoring for acute neurological changes during and immediately after angiographic procedures, even when only small amounts of contrast agents are used.
