Abdominal aortic aneurysm extending to the iliac bifurcation

The axial contrast-enhanced CT shows that the abdominal aortic diameter is normal at the level of the renal arteries (A, arrow), and well below the renal arteries (B). A fusiform dilation (C) begins at the level or the third lumbar vertebra and extends to the iliac bifurcation (D) but does not extend into the common iliac arteries. The sagittal view (E) shows the distal fusiform aneurysm with luminal thrombus.
