(A) - Bedside echocardiographic image (long parasternal axis view) showing signs of pericardial effusion (red *). (B) - Chest computed tomography showing circumferential pericardial effusion (red *) and mild left pleural effusion (yellow arrowhead). RA: right atrium; RV: right ventricle; LV: left ventricle.

Bedside echocardiogram showed circumferential pericardial effusion and respiratory variation in the intracardiac flows; all findings were consistent with increased intrapericardial pressure (Figure 1A). Chest computed tomography (CT) showed mild left pleural effusion and signs of circumferential pericardial effusion (Figure 1B).
Tuberculous bacilli (acid-fast bacilli, red circle) present within the pericardium infiltrate.
