case_images: A contrast-enhanced computed tomography (CT) image obtained 1 month before the detection of the thrombus showed no abnormalities in the ascending aorta.

case_images: CECT images obtained about 1 month earlier had not shown any abnormalities in the aorta (Figure 1); however, the new CT images incidentally revealed a floating mass in the ascending aorta (Figure 2).

case_images: fig2-2050313X20971894
case_images: CECT images obtained about 1 month earlier had not shown any abnormalities in the aorta (Figure 1); however, the new CT images incidentally revealed a floating mass in the ascending aorta (Figure 2).
case_images: Four-dimensional CT images showed that the mass was attached to the anterior wall of the ascending aorta and moved up and down in sync with the patient's heartbeat: (a) systolic phase; (b) diastolic phase.

case_images: fig3-2050313X20971894
case_images: A 36-mm-long part of the mass was moving up and down, and the movement was synchronized with the patient's heartbeat (Figure 3(a), (b) and Video 1, 2).
case_images: A hematoxylin-eosin stained specimen showed that the mass was a fibrin thrombus (arrows). The attachment site exhibited atherosclerosis; however, no continuity was found between the thrombus and tunica intima (1x).

case_images: The aortic wall exhibited evidence of atherosclerosis; however, no continuity was found between the thrombus and tunica intima (Figure 4).
