An unusual case of cardiac lymphoma diagnosed using computed tomographyguided percutaneous transthoracic biopsy

Cardiac tumors are the extremely rare and least investigated tumors in oncology. The most common type of tumor originating primarily in the heart is myxoma, while other types are sarcoma, lipoma, fibroelastoma, teratoma, lymphoma, and mesothelioma. Only 10% of cardiac tumors are malignant, and 95% of which are sarcomas and remaining 5% are lymphomas and mesotheliomas (1). Primary cardiac lymphoma (PCL) is a type of non-Hodgkin lymphoma, which originates from myocardium or pericardium and those are the only sites of involvement at the time of diagnosis. The patients are mostly, but not always, admitted with cardiac manifestations (2). PCL is very rare and fatal unless it is diagnosed and treated on time. Patients with PCL usually die few months after diagnosis (3, 4). In this article, we present a challenging case of PCL diagnosed using computed tomography (CT)-guided percutaneous transthoracic biopsy of the cardiac mass encircling the atrioventricular septum.
