Multimodal imaging evaluation of a primary cardiac lymphoma in an immunocompetent patient.

Primary cardiac lymphoma (PCL) is a rare extranodal lymphoma that involves only the heart and/or pericardium. It is fatal in the absence of a prompt diagnosis and adequate therapy. Here, we report an immunocompetent 55-year-old Chinese man with palpitations and occasional chest distress for 1 month. Multimodal imaging work-up showed a tumor infiltrated into the myocardium, which greatly contribute to a timely pathology diagnosis of PCL.
