A 62-year-old woman with no systemic disease presented to the emergency department (ED) with acute febrile illness for three days. During her ED course, she developed respiratory distress and refractory cardiogenic shock with ST-elevation on electrocardiography. No occluded coronary vessel was found in angiography, and perimyocarditis was impressed. The serum indirect immunofluorescence assay was positive for scrub typhus. Hemopericardium and subsequently intracranial hemorrhage occurred on the 4th hospital day even under intensive care, and the patient expired. Perimyocarditis is a rare but fatal complication of scrub typhus. Through this case report, we aim to convey the genuine possibility that a fulminant perimyocarditis may occur in a previously healthy adult as a potential complication of scrub typhus. By recognizing the risk factors of scrub typhus-related myocarditis, an ED physician can maintain a high index of suspicion for the cardiac complication and intervene in a timely manner.
