The spiked helmet sign in a patient with erysipelas: an alarming electrocardiogram sign: a case report

Abstract

Early diagnosis of the spiked helmet sign is challenging. This ST-elevation myocardial infarction mimic was first described in 2011 by Littmann and colleagues and was linked to severe non-coronary pathologies, with a high risk of mortality. We present a case of a 60-year-old female patient who developed severe erysipelas with sepsis associated with severe hypokalemia. She had a spiked helmet sign on her routine electrocardiogram at hospital admission. We performed a coronary angiogram that showed no culprit artery. She developed afterward an ischemic stroke. Through intensive management of the patient’s sepsis and electrolyte disturbance, she had a favorable outcome.
