Associated gastroduodenal artery aneurysm aortic aneurysm: the diagnostic contribution of contrast-enhanced ultrasound in correlation with computed tomography angiography.

Splanchnic aneurysms are rare conditions, with localization at the level of the gastroduodenal artery being encountered in only 1.5 % of the cases. Due to the high mortality risk, early detection and optimal treatment are required. We stress the importance of ultrasonography as a primary method of detection as well as the role of contrast-enhanced ultrasound in characterization of visceral aneurysms. Due to its noninvasive nature, the examination could be used for follow-up after therapeutic procedures or in cases were a curative intervention is not possible.
