Contrast media induced encephalopathy is a rare complication of contrast administration characterized by non-specific neurological signs and symptoms that may present both clinically and radiolographically as subarachnoid hemorrhage. While there are few reported presentations in the neurology literature after inpatient contrast administration, similar emergency department presentations have not been documented. We describe a patient who presented with encephalopathy and expressive aphasia after outpatient evaluation of an intrathecal analgesia pump who had radiographic imaging consistent with acute subarachnoid hemorrhage. The hyperdensities seen on computed tomography scanning were subsequently identified as residual gadolinium contrast media resulting in allergic encephalopathy in this patient.
造影剂诱导性脑病是造影剂给药的罕见并发症，其特征为非特异性神经体征和症状，在临床上和影像学上可能表现为蛛网膜下腔出血。虽然神经科文献中报道的住院患者造影后表现较少，但类似的急诊科表现尚未记录。我们描述了一名门诊评估鞘内镇痛泵后出现脑病和表达性失语的患者，其影像学表现符合急性蛛网膜下腔出血。计算机断层扫描显示的高密度影随后被确定为残留的钆造影剂，导致该患者发生过敏脑病。
