Although sonographic artifacts are common in sonography, they can create diagnostic challenges and even lead to critical diagnostic errors. The authors report a case of an echogenic artifact resembling an abdominal aortic thrombus. An awareness of the existence of this pseudothrombus and techniques to differentiate this artifact from an actual fibrinous clot may help avoid unnecessary anxiety and costly testing.

Key Words: abdominal aortic thrombus • sonography • echogenic artifact
