Does cardiac magnetic resonance imaging improve the differential diagnosis in patients presenting with chest pain, elevated troponin, and normal coronary arteries?
Cardiac magnetic resonance imaging is essential for the accurate differential diagnosis of acute myocarditis versus takotsubo syndrome in patients with MINOCA.

Supports CMR for myocarditis diagnosis in select MINOCA cases with apical ballooning; leaves open need for prospective trials.
Acute myocarditis is often misdiagnosed, and its evolution is not always benign; correct and prompt diagnosis is therefore essential. We report the case of a 62-year-old woman with chest pain after a stressful event and ST-segment elevation on the electrocardiogram, in whom urgent cardiac catheterization showed normal coronary arteries and left ventricular apical ballooning, suggesting takotsubo syndrome. However, cardiac magnetic resonance imaging showed lesions typical of acute myocarditis, thus suggesting this diagnosis. We highlight the diagnostic difficulty in patients with chest pain, elevated troponin and normal coronary arteries, and the key role of cardiac magnetic resonance in differential diagnosis. A miocardite aguda é uma entidade frequentemente subdiagnosticada e com uma evolução que nem sempre é benigna, pelo que o seu diagnóstico se torna mandatório. Apresenta-se o caso de uma mulher de 62 anos, com dor precordial anginosa após evento de stress emocional, associada a elevação do segmento ST no eletrocardiograma, cujo cateterismo cardíaco de urgência mostrou artérias coronárias normais e balonização apical do ventrículo esquerdo, sugestivo da síndroma de takotsubo. Contudo, a ressonância magnética cardíaca mostrou lesões compatíveis com miocardite aguda, revelando, assim, este diagnóstico. Destacamos a dificuldade diagnóstica no doente com dor torácica, elevação de troponina e artérias coronárias normais, em que a ressonância magnética cardíaca assume um papel fundamental no diagnóstico diferencial.
