case_images: Ultrasound image showing the tumor-like structure of the mycotic pseudoaneurysm in the ascending aorta, with a thick wall and low-echoic material deposition within. Single arrow: rupture site; Double arrows: mural thrombus, which showed up on the echocardiogram as low-echoic material deposition. The distance between the two crosses symbols was 2.94cm; The distance between the two crosshair symbols was 2.37cm.

case_images: A tumor-like structure measuring approximately 2.95 cm x 2.73 cm, with a thick wall and low-echoic material deposition within was present in this region (Figure 1).
case_images: Doppler ultrasound image depicting bidirectional low-velocity blood flow signals entering and exiting the pseudoaneurysm at the rupture site. Single arrow: rupture site, red blood flow signals indicates blood flow into the pseudoaneurysm; Double arrows: rupture site, blue blood flow signals indicates blood flow out of the pseudoaneurysm.
