A computed tomography scan showed multiple hepatic and pulmonary lesions, enlarged abdominal lymph nodes, and pleural and pericardial effusions concerning for advanced metastatic cancer of unknown primary origin (Figures 1A and 1B). An echocardiogram showed a large pericardial effusion with right ventricular (RV) diastolic collapse and 25% to 30% respiratory variation in Doppler mitral inflow concerning for cardiac tamponade (Figures 2A and 2B, Video 1).
2-Dimensional Echocardiography. (A) Apical 4-chamber and (B) short-axis views revealing massive pericardial effusion (asterisks). LV = left ventricle; RV = right ventricle.
