Rapidly improving acute myocarditis after a scorpion sting

Cases with scorpion sting envenomation have usually a benign course, but fatalities especially due to cardiovascular complications have been reported. Local reactions at the site of the sting, and as well as organ dysfunction due to the systemic effects of its toxin have been indicated. As a result of the toxic effects of the scorpion toxin on the cardiovascular system, hypertension, arrhythmias, myocarditis, acute heart failure, and pulmonary edema may occur. In this report, we present a 49-year-old male patient who was admitted to our hospital with acute pulmonary edema and respiratory distress following scorpion sting at the wrist. In this case, immediate improvement of diffuse left ventricular systolic dysfunction on presentation with medical treatment, and increased troponin levels in the absence of critical stenosis on coronary angiograms suggested the diagnosis of acute myocarditis associated with scorpion bite.
