A 69-year-old man with severe chest pain was admitted to our hospital. No evidence of acute
myocardial infarction (AMI) was seen on laboratory data, electrocardiogram (ECG), and ultrasonic
echocardiography (UCG). Contrast-enhanced computed tomography (CECT) was performed to
role out aortic dissection and pulmonary embolism (PE). CECT images showed the hypoenhancement
of posterior wall in the left ventricle. AMI was suspected based on the symptoms
and CECT imaging. Coronary angiography (CAG) was performed, and the left coronary angiogram
showed total occlusion of segment 13. Percutaneous cardiac intervention (PCI) was immediately
performed, and the patient was discharged 15 days after admission with no
complications. It is important to check the myocardial enhancement when we interpret CT
images of patients with chest pain.
