Churg-Strauss syndrome with cardiac involvement: case illustration and contribution of CMR in the diagnosis and clinical follow-up.

This report summarises three cases of Churg-Strauss syndrome (CSS) illustrating the diagnostic challenges associated with the cardiac manifestation of this disease. Here, we illustrate the role of cardiac magnetic resonance (CMR) for diagnosis and follow-up of CSS with a focus on new non-contrast T-weighted imaging sequences for quantification of myocardial scar tissue and quantitative T mapping techniques, which allow the detection of myocardial edema.
