This case highlights the utility of transthoracic echocardiography in detecting secondary cardiac tumors such as mediastinal lymphoma invading the right atrium.
TTE may detect rare cardiac invasion by mediastinal lymphoma; hypothesis-generating and should not yet change practice.
Primary cardiac tumours are an uncommon cause of intra-cardiac mass. Most common intra-cardiac mass is thrombus followed by infiltrating secondary cardiac tumours. These secondary tumours are more likely to invade the cardiac chambers when they arise from close vicinity of the heart. We report an unusual case of mediastinal lymphoma in a 55 years old lady presenting as an intra-cardiac mass in the right atrium, which was detected by a transthoracic echocardiogram and later confirmed with more specific modalities.
