We present a case of a 32-year old patient with acute recurrent perimyocarditis associated with thyrotoxicosis. To the best of our knowledge, this is the first reported case of acute recurrent pericarditis associated with increased thyroid hormones in the bloodstream and accompanied by a significant increase in cardioselective enzymes and reduced ejection fraction. Although some authors have described a single episode of myopericarditis mimicking acute coronary syndrome, it was not recurrent. Clinical improvement and normalization of laboratory results following the successful management of thyrotoxicosis, suggests a possible link between these two clinical entities-myopericarditis and thyrotoxicosis.
