case_images: The electrocardiogram (ECG) showed sinus tachycardia, normal electrical heart axis and normal PR- and QRS-intervals, but inverted T-waves in both antero- and inferolateral leads (Figure 1). A further decrease in hemoglobin (4.7 mmol/L) was noted and TTE showed recurrent circumferential pericardial effusion (~3 cm) but now a dense structure suggesting thrombus in the pericardial sac (Figure 1). On the delayed enhancement (DE) images, the high intra-pericardial signal again suggested contrast-extravasation into the pericardial sac, whereas an extensive, hypo-enhanced circumferential layer against the inner parietal pericardium suggested thrombus (Figure 1).
