Ultrasound of an abdominal aortic aneurysm

The ultrasound examination of the abdominal aorta is shown in transverse projection (A) with Doppler interrogation (B) and reveals an abdominal aortic aneurysm measuring 4.75 cms in maximum transverse diameter. Turbulent flow in the aneurysm is reflected in the non-uniform heterogeneous Doppler pattern.
