It may be indistinguishable from myocardial ischemia so it is called “infarct-like pattern.” Cardiovascular magnetic resonance has an important role as a non-invasive diagnostic tool. The aim of our study is to provide a description of an acute myocarditis series with infarct-like pattern and to evaluate the cardiovascular magnetic resonance role in a pediatric population. We included all pediatric patients (0–16 years) admitted to our hospital (May 2007–May 2016) with clinical diagnosis of acute myocarditis and infarct-like presentation (chest pain, EKG alterations, and released cardiac biomarkers). Diagnosis was confirmed with cardiovascular magnetic resonance using Lake Louise criteria. Seven patients (five males, two females) with a median age of 14 years (12.5–15.2) were included. All patients showed ST-segment changes and released cardiac biomarkers. Three patients had left ventricular hypertrophy and two presented mild systolic left ventricular dysfunction. All patients had at least two positive Lake Louise criteria. Late gadolinium enhancement was positive in all of them. With a median follow-up of 23 months (8–47), all of them are alive, with no cardiac symptoms and normal ventricular function. Infarct-like pattern is a typical presentation of acute myocarditis in adolescents. CMR should be performed in this population and may be considered as a first-line diagnostic tool. Its high sensitivity in infarct-like acute myocarditis may allow us to avoid endomyocardial biopsy. Unlike what was described in adults, late gadolinium enhancement does not imply worse outcome in our series.
