Metastatic Sarcoma causing Cardiac Tamponade on POCUS This 50 yo man had an aggressive sarcoma with cardiac and pulmonary involvement. P/w respiratory failure. Echo shows evidence of tamponade - RV and RA compression BUT it was from a large fluid filled mediastinal mass. Surgery was not an option, he was transitioned to hospice Dr. Michael I. Prats @PratsEM Distorted anatomy: RVOT is pushed posteriorly, by a fluid filled structure pressing on the RV free wall. No pericardial effusion seen in region behind PWLV. #Sarcoma #malignant #cancer #Cardiac #Tamponade #POCUS #clinical #echocardiogram #plax
