Diagnosis of acute myocarditis with myocardial delayed enhancement on CTA: a case report

The diagnosis of acute myocarditis requires the exclusion of coronary artery disease (CAD). Coronary CTA (computed tomography angiography) is usually used to evaluate the coronary arteries in young patients. However, the use of coronary CTA for the diagnosis of myocarditis has been rarely reported. Here we present a Han male clinical myocarditis patient who was 18 years old, had a focus of enhancement in the subcardia, and predominantly involving the lateral wall of the left ventricle with iodinated contrast in coronary CTA. The patient was diagnosed with myocarditis. Immunoglobulin, vitamin C antioxidant, and myocardial nutrition were given to the patient for treatment. During follow-up, the patient’s myocardial enzymes gradually decreased to normal, and the original symptoms disappeared. As a non-invasive rapid examination method that can evaluate coronary artery and myocardial lesions at the same time, the utility of myocardial delayed enhancement on CTA may warrant further investigation.
