case_images: Left coronary angiography in the caudal view and right coronary angiography in the left-anterior oblique and cranial view. (a) Left coronary angiography in the caudal view showed a severe stenosis of the proximal segment of left anterior descending (LAD), following by a huge coronary aneurysm at the proximal middle segment of LAD. (b) Transversal diameter of 8.8 +- 1.0 mm and longitudinal diameter of 24.5 +- 2.6 mm. (c) Right coronary angiography in the left-anterior oblique and cranial view showed a severe stenosis of the middle segment of right coronary artery (RCA), following by a huge coronary aneurysm at the middle segment of RCA. (d) Transversal diameter of 5.9 +- 0.8 mm and longitudinal diameter of 10.5 +- 1.2 mm.

case_images: CAG was performed, and the results showed a sizeable aneurysmal dilatation in the LAD with 95% localized stenosis, 100% occlusion of the LCXp, and a sizeable aneurysmal dilatation of the RCA with 90% localized stenosis (Figure 1).
case_images: Huge coronary aneurysm observed during coronary artery bypass grafting (CABG) surgery; left anterior descending (LAD) aneurysm (red arrow); D1 aneurysm (yellow arrow).

case_images: The pathological examination of the left internal mammary artery (LIMA) confirmed minor lesions of endovascular inflammation in the LIMA and fibroproliferative degeneration around the vessel wall (Figure 3).
case_images: (a) Aortic CT angiography; splenic artery aneurysm (yellow arrow); common hepatic artery aneurysm (red arrow); gastroduodenal artery aneurysm (blue arrow). (b) Celiac artery angiography, splenic artery aneurysm (yellow arrow); common hepatic artery aneurysm (red arrow); gastroduodenal artery aneurysm (blue arrow).

case_images: The largest one was 3.6 cm x 3.7 cm x 3.7 cm, and it was located in the splenic artery (Figure 4a). Abdominal angiography showed aneurysmal-like structures in the hepatic artery, splenic artery, and gastroduodenal artery (Figure 4b), but no spillover of contrast medium was noted.
