Scorpion envenomation (SE) represents a major public health issue, since more than one million cases occur every year, especially in tropical, subtropical and sub-Saharan areas. Clinical presentation varies from pain at site of sting to severe generalized intoxication. Cardiac involvement, usually reversible within the first week post-sting, has been reported with different degrees of acute left ventricle (LV) dysfunction. Despite cardiac magnetic resonance (CMR) imaging is recommended, when available, transthoracic echocardiogram (TTE) still remains an excellent tool for diagnostic and follow-up assessment. We report herein an interesting and unusual case of prompt recovery of severe acute myocarditis secondary to SE in a young woman.
