Coronary artery intramural hematoma causing myocardial infarction mimicking pseudoaneurysm or dissection from trauma: A case report.

Blunt chest trauma caused ST-segment elevation myocardial infarction. Diagnosis of intramural hematoma (IMH) using computed tomography was confirmed using electrocardiography, cardiac marker tests, and subsequent coronary angiography. After conservative treatment, the hematoma was completely resolved 1 year later. Differentiating IMH from other arterial injuries is critical for appropriate management.
