case_images: Axial view of coronary computed tomography angiography study without contrast. Arrow 2 indicates pericardial drain. Circle 1 shows the Hounsfield units in the surrounding area is 38.4, consistent with hemopericardium.

case_images: On the non-contrast CCTA study, a large circumferential pericardial effusion was noted, most prominent on the lateral aspect of the left ventricle with 38.4 Hounsfield Units (HU) in the area which was consistent with hemopericardium (Figure 1).
case_images: Axial view of coronary computed tomography angiography study with contrast. Arrow 1 indicates the pseudoaneurysm measuring 1.7 cm, which is contained by pericardium at arrow 2 noted at the neck of the apical septum of the left ventricle, consistent with hemopericardium. There is circumferential pericardial effusion at arrow 3. Circle 4 shows an increase in Hounsfield to 120, indicating active extravasation.

case_images: fig2-11795468241249059
case_images: The contrast-induced increase in HU in the hemopericardium indicated ongoing extravasation from the pseudoaneurysm into the hemopericardium (Figure 2).
case_images: Short axis view of coronary computed tomography angiography study with contrast. Arrow indicates broad based aneurysm in the left ventricle.
