Nonpenetrating chest trauma may result in significant myocardial contusion, a diagnosis which may not be considered due to the apparent "triviality" of the trauma, or may be initially overshadowed by more visible injuries. The presence of myocardial contusion may only become apparent through developing complications and rarely may be lethal. Its incidence in closed chest trauma has been reported to be 6-76% [1, 2]. This confusion exemplifies the lack of agreement as to criteria for diagnosis. Children present additional and unique problems, which our case report illustrates.
