[Anomalies in myocardial contrast uptake revealed by multislice cardiac CT during acute myocarditis]

Acute myocarditis can display many various clinical appearances. Endomyocardial biopsy is an invasive investigation for which the sensibility is insufficient in mild cases and when it is performed too early. Multislice cardiac CT with ECG synchronisation and injection of contrast medium allows visualisation of the coronary arteries and the study of myocardial contrast uptake. We report the cases of two patients with a mild myocarditis where multislice CT performed early showed multiple areas of increased myocardial contrast uptake consistent with a diffuse inflammatory disorder. Coronary angiography was normal in these two patients. Multislice cardiac CT could be a useful non-invasive investigation for the early diagnosis of this disease.
