Case A 47‐year‐old man was admitted after a car collision in shock with cardiac tamponade. After his circulation was stabilized by pericardial drainage, we treated him conservatively. Abnormal laboratory data and initial electrocardiogram ( ECG ) were suggestive of myocardial injury. However, echocardiography and cardiac computed tomography could not reveal the cause of the tamponade or the site of cardiac injury. ECG ‐gated cardiac magnetic resonance images were acquired. Outcome The cardiac magnetic resonance black‐blood T 2‐weighted images showed hyperintense signals in the interventricular septum, whereas the late gadolinium enhancement images showed no enhancement in this region. We could accurately diagnose cardiac contusion of the anteroseptal area, which would explain the initial ECG abnormality seen in this patient. Conclusion Cardiac magnetic resonance imaging may be especially useful in the evaluation of non‐operative management of blunt cardiac injury and could explain the initial ECG abnormality seen in our patient.
