Pericardial versus pleural effusion. a Parasternal long axis view. Pericardial effusion (asterisks) tracks anterior to the descending aorta (da); LV left ventricle, LA left atrium, RVOT right ventricle outflow tract, Aor aortic root. b Apical 4-chamber view. Pericardial effusion (asterisk) tracks anterior to the descending aorta (da); pleural effusion (white star) tracks posterior and lateral to the da. Arrows pericardial delineation, L lung consolidation, LV left ventricle, RV right ventricle, RA right atrium. c Pleural effusion (white star) tracks posterior and lateral to the da; L lung consolidation, LV left ventricle, LA left atrium, RVOT right ventricle outflow tract, Aor aortic root. d Right pleural effusion (asterisk) extending into the bare area of the liver, besides the heart in subcostal 4-chamber view; L lung consolidation, RA right atrium, RV right ventricle, LA left atrium, LV left ventricle, da descending aorta
