case_images: Preoperative chest CTA images of the patient. (A) The axial section shows a spherical high-density contrast-filled image (black asterisk). (B) Oblique coronal section revealing a rupture measuring 1.6 x 2.0 cm at the right coronary sinus (white arrow). CTA = computed tomography angiography.

case_images: An emergent chest computed tomography angiography (CTA) revealed moderate pericardial effusion and a large spherical pseudoaneurysm measuring 7.5 x 7.0 x 6.3 cm in the right atrioventricular groove (Fig. 1). Additionally, a rupture measuring 1.6 x 2.0 cm was identified in the right coronary sinus of the ascending aorta (Figs. 1B and 3B).
case_images: Postoperative chest CTA images of the patient. Postoperatively, the pseudoaneurysm's rupture site was successfully sealed with a pericardial patch. CTA = computed tomography angiography.

case_images: The CTA also demonstrated excellent visualization of the left anterior descending and left circumflex coronary arteries, although the proximal segment of the right coronary artery was not visible, while the distal segment was well visualized (Fig. 2).
case_images: Cinematic renderings based on CTA. (A) Showing a pseudoaneurysm located in the right atrioventricular groove area (white asterisk) and (B) displaying a rupture of 1.6 x 2.0 cm in the right coronary sinus of the ascending aorta (white arrow). After surgery, (C) shows that the pseudoaneurysm channel had closed. CTA = computed tomography angiography.
