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.

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).

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).
(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).

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.
