Mycoplasma Pneumonia as a Rare Culprit in Acute Myocarditis

Mycoplasma pneumoniae (M. pneumoniae) is an atypical bacterium transmitted by respiratory droplets through close contact. It is a common cause of community-acquired pneumonia, with an overall mortality rate of approximately 30%. Besides respiratory symptoms, M. pneumoniae can cause extrapulmonary complications including myocarditis in 1%-5% of cases leading to arrythmias and heart failure. We are introducing the case of a 16-year-old boy who presented with acute chest pain, due to myocarditis related to Mycoplasma pneumoniae, an unsuspected cause of myocarditis. This case underscores the importance of considering atypical pathogens in myocarditis cases and emphasizes the need for comprehensive diagnostic approaches to guide timely and appropriate therapeutic interventions for rare presentations of cardiac involvement due to Mycoplasma pneumoniae.
