case_images: A 55-year-old male with confirmed IgG4 vasculopathy. Axial maximum intensity projection (MIP) image of CT coronary angiography shows partially thrombosed aneurysm of the left anterior descending artery (arrows).

case_images: Ingenuity CT after intravenous injection of 80 ml of non-ionic contrast media, for the evaluation of the exertional dyspnea and atypical chest pain. It showed a giant partially thrombosed aneurysm of the proximal - mid-left anterior descending (LAD) artery [Figure 1] which was more clearly depicted in the volume rendered image [Figure 2], a partially thrombosed aneurysm of the proximal part of 8th right intercostal artery [Figure 4].
case_images: A 55-year-old male with confirmed IgG4 vasculopathy. Volume rendered image shows the aneurysm of the left anterior descending artery (in pink).

case_images: A 55-year-old male with confirmed IgG4 vasculopathy. The right anterior oblique caudal view of conventional angiography shows aneurysmal dilatation of the left anterior descending artery with contrast blush (*).

case_images: The patient underwent conventional angiography which showed aneurysmal dilatation of LAD with contrast blush [Figure 3], followed by surgical resection of the aneurysm of LAD artery.
case_images: A 55-year-old male with confirmed IgG4 vasculopathy. Coronal maximum intensity projection images of CT abdominal angiography in arterial (left) and venous (right) phases show partially thrombosed aneurysm in the proximal part of 8th right intercostal artery (*). Enhancing nodular paravertebral soft-tissue thickening is noted adjacent to the proximal right intercostal arteries above and below this level.

case_images: Ingenuity CT after intravenous injection of 80 ml of non-ionic contrast media, for the evaluation of the exertional dyspnea and atypical chest pain. It showed a giant partially thrombosed aneurysm of the proximal - mid-left anterior descending (LAD) artery [Figure 1] which was more clearly depicted in the volume rendered image [Figure 2], a partially thrombosed aneurysm of the proximal part of 8th right intercostal artery [Figure 4]. Nodular paravertebral soft-tissue thickening adjacent to the proximal parts of 6th-10th intercostal spaces was noted [Figure 4].
case_images: A 55-year-old male with confirmed IgG4 vasculopathy. Axial image of CT abdominal angiography in the arterial phase shows a partially thrombosed aneurysm in relation to the common hepatic artery. Artifacts are seen in relation to the aneurysm (post-injection in the gastroduodenal artery). The aortic stent graft is also seen in situ.

case_images: CT abdominal angiography was also performed the next day, which revealed multiple aneurysms of the celiac axis, the common hepatic artery [Figure 5], inferior pancreaticoduodenal artery, and the jejunal branch of superior mesenteric artery [Figure 6].
case_images: A 55-year-old male with confirmed IgG4 vasculopathy. Coronal maximum intensity projection image of CT abdominal angiography shows multiple visceral artery aneurysms - in relation to the common hepatic artery (black arrow), inferior pancreaticoduodenal artery (white curved arrow), and the jejunal branch of superior mesenteric artery (white arrow). Artifacts are noted in relation to the gastroduodenal artery, aorta, and the superior mesenteric artery - representing stent grafts and post-procedural changes. Cholecystectomy clips are also seen.
