造影剂诱发的脑病是一种罕见的可逆现象，已知发生在静脉或动脉内造影剂暴露后。本报告描述了一例73岁女性患者因择期胸主动脉瘤修复术入院。在手术过程中，动脉造影需要大量的非离子碘造影剂。术后，患者出现癫痫发作活动，随后出现左侧偏瘫。无造影剂的脑部计算机断层扫描（CT）和磁共振成像（MRI）显示急性卒中阴性，但显示脑周围有残留造影剂。给予抗癫痫药物，癫痫发作活动消退。患者接受支持性治疗，在接下来的7天内改善至基线水平。本病例显示一种罕见的非离子型碘造影剂诱发的脑病，伴有癫痫发作和短暂性偏瘫。独特的影像学表现将其与其他神经系统疾病区分开来。
Contrast-induced encephalopathy is a rare, reversible phenomenon known to occur after intravenous or intra-arterial contrast exposure. This report describes a case involving a 73-year-old female admitted for an elective thoracic aortic aneurysm repair. During the procedure, a large volume of nonionic iodinated contrast was necessary for arteriography. Postoperatively, the patient developed seizure activity followed by left-sided hemiplegia. Computed tomography (CT) of the brain without contrast and magnetic resonance imaging (MRI) were negative for acute stroke but did show residual contrast surrounding the brain. Antiepileptic medications were administered with resolution of the seizure activity. The patient was treated with supportive management and improved to baseline over the next seven days. This case demonstrates a rare, nonionic iodinated contrast-induced encephalopathy with seizure activity and transient hemiplegia. The unique imaging findings differentiate it from other neurologic conditions.
