Elongated inferior vena cava and intracardiac mass: Thrombus in-transit or metastasis

Abstract

Cardiac masses are rare entities categorized as either neoplastic or non-neoplastic. We present a case of cardiac mass from the inferior vena cava (IVC) extending to the right atrium, right ventricle and pulmonary artery that was diagnosed by computed tomography (CT), transthoracic echocardiography (TTE), and cardiovascular magnetic resonance (CMR) imaging. Differential diagnosis of a right atrial mass includes myxoma, thrombus, renal cell carcinoma and metastatic cardiac tumor. This case emphasizes the importance of multi-modal imaging during diagnostic work-up when a cardiac mass of unknown origin is present.
