Contrast-induced encephalopathy (CIE) is a rare complication of imaging using ionidated contrast media. Its pathogenesis remains unknown, and its clinical presentation is variable. We present two cases of CIE following coronary angiography (CAG) that underscore the multitude of clinical manifestations and imaging findings associated with the disorder.

A 72-year-old female with a history of hypertension and hyperlipidemia presented to the emergency department from an outside hospital with acute confusion and global amnesia immediately following cervical epidural steroid injection with fluoroscopic guidance for radiculopathy relief. On exam, she was oriented to self, but disoriented to place and situation. Otherwise, she was neurologically intact with no deficits.

The present study describes the case of patient with contrast-induced encephalopathy following cerebrovascular angiography, and presents the clinical and imaging features, as well as the treatment and prognosis of this patient. Following digital subtraction angiography, cortical blindness and cognitive dysfunction were the main complaints of the patient. The emergency craniocerebral CT scan revealed hyperdense areas in the bilateral cerebellum, thalamus, sulcus and cistern, and a review of the CT scan 24 h following the procedure revealed that the hyperintense lesions were reduced or resolved in these areas.

Introduction: Contrast-induced encephalopathy represents a rare, reversible complication that appears after intravenous or intra-arterial exposure to contrast agents. There is no consensus in the literature regarding the mechanism of action. However, the theoretical mechanism is set around the disruption of the blood-brain barrier and the contrast agents' chemical properties.
