Autoimmune limbic encephalitis mimicking inferior myocardial infarction on ECG.

Abstract

A man in his 60s with prior history of coronary artery bypass graft was found collapsed, unresponsive on the floor by family. ECG demonstrated an inferior ST elevation myocardial infarction. However, coronary angiography was negative for a culprit lesion. A faciobrachial dystonic seizure was witnessed during his hospitalisation, ultimately leading to a diagnosis of leucine-rich glioma-inactivated 1 (LGI-1) autoimmune encephalitis. It is likely that neurogenic stunned myocardium led to this presentation.
