title: Three-dimensional CT in isolated dissecting aneurysm of the superior mesenteric artery: a case report.
abstract: Isolated dissecting aneurysm of the superior mesenteric artery (SMA) without aortic dissection is a rare condition. We report a case of isolated dissecting aneurysm of the SMA incidentally detected by postcontrast abdominal computed tomography (CT). Three-dimensional CT using helical scanning was helpful for the evaluation of dissecting aneurysmal structures such as the intimal flap, true lumen, and false lumen with thrombosis. CT angiography (CTA) was useful for the assessment of characteristic morphology and three-dimensional relationship between the dissecting portion and SMA branches.
