Figure 1. (a) Electrocardiogram done on presentation, demonstrating sinus tachycardia with relatively low voltages. (b) Bedside echocardiogram done on presentation, with a parasternal view demonstrating circumferential pericardial effusion (arrow). (c) M-mode ultrasonography demonstrating early right ventricular collapse during diastole (arrow).

Figure 3. (a) Coronal CT scan of the thorax with IV contrast demonstrating moderate-large pericardial effusion and fluid collection within the right thorax with surrounding calcifications, with mediastinal shift (arrows). (b) Axial CT scan of the thorax with IV contrast demonstrating right-sided fluid collection with calcifications as well as the pericardial effusion (arrows). CT: computed tomography; IV: intravenous.
