The diagnosis of acute myocarditis (AM) remains challenging because of its diverse clinical manifestations. Thus, a wide range of diagnostic tests may be warranted. Although cardiac magnetic resonance (CMR) is the preferred imaging technique, it may not be applicable in the acute AM phase. Our case report highlights the usefulness and diagnostic accuracy of echocardiographic examination. In the first 2-dimensional echocardiography, the focal echobright was presented. A reduced value of global longitudinal strain and regional disturbances of segmental myocardial strain, both longitudinal and circumferential, in the epicardial layer, were detected with a good correlation with CMR results.
