Fig 1 (A) Contrast-enhanced computed tomographic scan of chest demonstrates large ruptured intercostal artery aneurysm in patient’s right thorax, with mass effect on left atrium and esophagus. Nasogastric tube can be seen in esophagus anterior to aorta. (B) Additional intercostal artery aneurysm arising from tortuous left intercostal artery at same level of ruptured right intercostal aneurysm is noted. (C) Intraoperative photograph of the ruptured right intercostal artery aneurysm. (D) Ex vivo photograph of 6-cm ruptured right intercostal artery aneurysm (left). Note clot adherent to site of rupture on left side of aneurysm. Smaller 4-cm unruptured right intercostal artery aneurysm was also excised (right).

Fig 2 (A) Selective left T7 intercostal arteriogram demonstrating large proximal intercostal artery aneurysm and tortuous intercostal artery. (B) Coil embolization of another left intercostal artery aneurysm. Three of 4 left intercostal artery aneurysms were successfully embolized. (C) Computed tomographic scan 6 months later showing enlargement of fourth left intercostal artery aneurysm from 3.7 to 5.1 cm, with a larger contrast swirl within lumen. (D) Angiogram of same aneurysm shown in C, which could not be embolized.
