CTICasesTraumatic Myocardial Contusion
Imaging findings
Abdominal CT and subsequent non-sedated, non-gated cardiac CT angiogram in a pediatric patient demonstrate decreased myocardial perfusion and attenuation in the distal left ventricular inferior wall and apex. An associated simple-appearing pericardial effusion is also present.
Key takeaways
Blunt chest trauma can result in direct myocardial injury or contusion, even in pediatric patients involved in medium-energy mechanisms. This can manifest with transient perfusion abnormalities on CT, wall motion abnormalities on echocardiography, elevated troponin, and pericardial effusions.
