CTICasesAcute viral myocarditis
Imaging findings
Chest radiograph and CT show diffuse pulmonary edema, pleural effusions, and a hemopericardium. Cardiac MRI demonstrates reduced left ventricular ejection fraction and extensive, patchy late gadolinium enhancement in a subepicardial and mid-myocardial distribution involving the lateral, inferolateral, and septal walls.
Key takeaways
Acute myocarditis typically affects young patients, presenting with chest pain, dyspnea, elevated troponins, and heart failure. Cardiac MRI is the gold standard for non-invasive diagnosis, showing characteristic non-ischemic subepicardial or mid-myocardial late gadolinium enhancement.
