case_images: Computed tomography (CT) angiography of her chest confirmed the AAC placement and ruled out acute pulmonary embolism [Figure 1].
case_images: MUGA scan showing blood flow to the ascending aorta and the aortic arch, the AAC to the descending aorta (black arrow), and an incidental finding of a pseudoaneurysm (white arrow)

case_images: To evaluate cardiac function and to assess the probable occlusion of the AAC, a multiple-gated acquisition (MUGA) scan was performed that showed blood flow to the ascending aorta and the aortic arch, the AAC to the descending aorta [Figure 2, black arrow], and an incidental finding of a pseudoaneurysm [Figure 2, white arrow].
case_images: Gray scale and color images of the phase analysis, before aneurysmectomy, showing two peaks on the histogram. The first peak is likely to be the result of synchronous conduction between the atria and the pseudoaneurysm, which can explain the absence of three distinct peaks. The second peak represents ventricular conduction

case_images: The phase analysis [Figure 3] showed only two peaks, likely due to synchronous conduction of the atria and the pseudoaneurysm (first peak).
case_images: MUGA scan after aneurysmectomy, showing blood flow to the aortic arch and the AAC (black arrow); the pseudoaneurysm is no longer seen

case_images: A follow-up MUGA scan after aneurysmectomy was performed, which showed blood flow to the aortic arch and the AAC [Figure 4, black arrow]; the pseudoaneurysm was no longer seen, and the patient was noted to be asymptomatic at that time.
case_images: Gray scale and color images of the phase analysis, after aneurysmectomy, showing two peaks on the histogram. The first peak represents ventricular conduction and the second peak represents atrial conduction

case_images: The phase analysis performed after aneurysmectomy showed an expected two distinct peaks corresponding to the ventricular conduction and atrial conduction, respectively, [Figure 5].
