title: Mycotic abdominal aneurysm: report of a case with emphasis on the presence of gas echoes.
abstract: Mycotic abdominal aneurysm is a relatively rare disease and its sonographic (US) findings have rarely been reported. We present a case of mycotic aneurysm of the common iliac artery in which the initial US showed a slightly wall-thickened abdominal aorta with gas echoes in the wall, a second US 6 days later showed a rapid increase in aortic size, and an emergent surgical intervention showed a mycotic aneurysm. This interesting observation suggested that the presence of gas echoes is a useful US finding indicating the beginning of a mycotic aneurysm and, when encountering this US finding, that emergent treatment should be considered to prevent delay in patient management.
