Multidetector spiral CT renal angiography in the diagnosis of giant renal artery aneurysms.

A case of giant renal artery aneurysm in a 63-year-old man is presented. Renal artery aneurysms are rare (incidence < 1%) and this case is one of the largest giant renal artery aneurysms recorded in the literature. This case also demonstrates the value of multidetector spiral computed tomographic renal angiography in the diagnosis, planning, and treatment of renal aneurysms.
