Rare Case of Cardiac Hemangioma Causing Massive Pericardial Effusion

A 35-year-old woman presented to the emergency room with a 2-month history of general malaise and anasarca. The chest x-ray showed cardiomegaly, and transthoracic echocardiography revealed massive pericardial effusion leading to cardiac tamponade (Figure 1A and 1B). Immediately, 1400 mL pericardial effusion (yellow exudate) was removed by needle pericardiocentesis. After the procedure, transthoracic echocardiography showed an immobile, heterogeneous tumor in the left atrium (LA) (Figure 1C and Movie I in the online-only Data Supplement).Figure 1. Multimodality imaging of the left atrial (LA) tumor. Transthoracic echocardiography revealed massive pericardial effusion leading to cardiac tamponade ( A and B ). After removal of the pericardial effusion, the immobile, heterogeneous tumor was observed in the LA ( C and Movie I in the online-only Data Supplement). Cardiac computed tomography (CT) showed a well-circumscribed tumor located in the LA wall near the origin of the left pulmonary veins ( D and …
