Primary Cardiac Lymphoma: Diagnosis and the Impact of Chemotherapy on Cardiac Structure and Function.

We report a case of primary cardiac lymphoma presenting as myopericarditis and rapidly deteriorating into biventricular heart failure and ventricular arrhythmias. Computed tomography and cardiac magnetic resonance (CMR) imaging showed extensive myocardial infiltration with typical patterns on tissue characterization CMR images, raising clinical suspicion. Diagnosis was confirmed by myocardial histologic examination.
