A Case Report of Pericardial Effusion with False-Positive Mesothelioma and Adenocarcinoma Markers as the Initial Presentation of Systemic Lupus Erythematous

Figure 2

Initial transthoracic echocardiogram obtained on admission shows a large circumferential pericardial effusion measuring 2.24 cm (red line). Cardiac tamponade is present, evinced by early right ventricular diastolic collapse, significant respirophasic variation of mitral inflow and IVC dilation with decreased respiratory variation consistent with elevated right atrial pressure.
