case_images: Cardiac MRI images (case 1). (a) Images of postpericardiocentesis showing pericardial thickening with pleural effusion (arrows). (b) Eight weeks later following treatment with steroids and colchicine.

case_images: Subsequent magnetic resonance imaging (MRI) showed pericardial thickening with evidence of acute pericardial inflammation suggestive of acute pericarditis (Figure 2).

case_images: A moderate pericardial effusion with measurements of 1.25 cm adjacent to the right ventricular (RV) free wall, 1.44 cm adjacent to the lateral wall, and 1.24 cm encircling the right atrium (RA). In addition, the left ventricle (LV) displayed diminution, exhibiting midcavity obliteration and generating a late systolic peak gradient of 41 mmHg at rest. Calcification was observed in the mitral and aortic valves, each showing mild stenosis causing some degree of hemodynamic compromise.

case_images: (a) Pericardial effusion measuring 1.5 cm posterior and 1 cm anteriorly not causing hemodynamic consequences. (b) One week later: the pericardial effusion has increased in size and is now causing hemodynamic compromise (case 3).

case_images: Although cardiac examination and 12-lead electrocardiograms were normal, echocardiography revealed a mild to moderate circumferential pericardial effusion and reaccumulation of pleural effusions (Figure 4(a)). After a week of observation, the effusion had enlarged (Figure 4(b)) and was now hemodynamically compromising.
